Problem in binding the bridge to Infiniband card

Hi there,
We are running Oracle VM Server 2.2 on HP Blade with Mellanox card installed in it. We are trying to use the infiniband card for higher speed but are unable to bind any bridge to this interface.
Mellanox drivers are installed and the device is working fine. Below is the error i get while trying to bind the bridge
# brctl show
bridge name bridge id STP enabled interfaces
xenbr0 8000.001b7831a5c6 no vif3.0
tap3.0
eth0
xenbr1 8000.001b7831a582 no eth1
xenbr2 8000.000000000000 no
# brctl addif xenbr2 ib0
can't add ib0 to bridge xenbr2: Invalid argument
Your help is appreciated.
Thanks!

Only devices with a promiscuous mode can participate in a bridge. Looks like either IB is one of them or the driver is broken. Run the command:
# /usr/bin/strace -o ib-log.txt -TttFf brctl addif xenbr2 ib0This should show us the ioctl(2) which is being rejected, maybe shedding some light on this topic.

Problem two - replacing the fan on video card

I have a NVidea GeForce4 Ti video card in my G4. The fan cooling the GPU stopped spinning, although I don't know when. I ordered the identical fan on-line, thinking that it wouldn't be that hard to get the old fan off. Apparently, it isn't as easy as I thought. There are two black plastic pieces which springs connecting the fan/heatsink to the board. For the life of me, I can't figure out how to extract them.
So, then I thought about just removing the fan and leaving the original heat sink attached. I got 6 of the 7 screws out, but one's really tight. Assuming that I can eventually get that one out as well, I still need to extract the wires from the surface of the card... it appears that they are glued on in one spot.
Has anyone here tried changing the fan on this (or another) video card who might have some insights in how to proceed? Thanks in advance for your help!

I purchased my replacement fan from "Surplus Sales of Nebraska." They actually carry the fan originally installed on the card. There website is:
www.surplussales.com
and the part number was FAN-MTHERM1027B
If you google "NV-1035-C2", it should pop right up (I get is as the first hit). They're only $6, but they have a $10 minimum order. I ended up with two fans.
I've been busy, so I haven't tried removing the fan yet. I read on the web, though, that once you remove the two black plastic pieces, you should put the video card into a freezer bag and then place it in the freezer for a few hours. Supposedly, you can then remove the fan with a twisting motion. Apparently, it's pretty easy to damage the GPU if you pull it straight off. That being said, if you can remove all of the screws on the fan, you can actually leave the heatsink in place and just replace the fan. I tried that, but I have one screw that's stuck.
Anyway, I think this is still the least of my problems. Although I haven't tried rebooting recently, I had trouble mounting a DVD today which I suspect is related to my first problem (where my hard drives don't always show up when I try to boot the computer). I'm becoming convinced that it's going to be a power supply or motherboard issue (ugh). If I get a chance to try removing the fan from the board, I'll let you know.

My hp dm3-3027cl card reader can not recognize the class 10 sdhc card

My hp dm3-3027cl card reader can not recognize the class 10 sdhc card. I downloaded and installed the card reader driver from HP web site for this dm3-3027cl, but still have same problem. There isn't a problem on class 6 SDHC card. It seems some other computers have the same problem on reading the class 10 SDHC card. My toshiba e105 laptop has no probblem to read class 10 SDHC card.

Hello snowman90024 and welcome to community,
Kindly install the USB and card reader driver then install cardreader driver and USB driver
Please let us know about the status after this.

When executing the layout after doing the binding, the detail fields in the form is repeating itself on all the rest of the rows for that column???

Is the cardinality on the context correct? Have you tried displaying this same context using a web dynpro table instead?

Hi..
You can email Apple for help but the link is for the iTunes store not the Mac App Store. You've inadvertently poasted in the Using Mac App Store forum but that's ok. Billing issues are the same for the iTunes Store.

Your credit or debit card credentials must be associated with the same country where you reside.

ACR and the Bridge thumb regeneration problem.

I just installed the 8.4 RC version of ACR to see if it fixed a bug that appeared back in version 7.2. It did not.
The bug appears in Bridge where Bridge randomly and repeatedly regenerates thumbnails. The bug is discussed in several threads on the Adobe Bridge forum. It is a difficult and mysterious bug because it appears to effect only a few people (maybe others don't notice). And those affected report different suspected causes.
Everyone in those threads assume the bug is within Bridge. But in my case, I believe the bug is caused by ACR.
In my version of the bug (Bridge CC on Win7) when I point Bridge at a folder of images, the progress wheel in the bottom left corner will spin and report "xxx thumbnail extractions" while xxx counts down. If I leave that folder and return later (with no changes made to the images) it will regenerate thumbnails and count down again. But not for the entire set of images, just some of them. By "return later" I mean 1 second later.
I've saved proir versions of the "Camera Raw.8bi" file. If I use version 7.1.0.354 of Camera Raw, regeneration of thumbnails ceases. Any version greater than 7.1 causes regeneration.
I have a theory, but ask for help or comment on the likelihood of my theory.
When Bridge scans the images in a folder and compares them to the existing thumbnails in the cache, that comparison has to involve dates. If the date of a thumbnail file is different than the date of the image file, Bridge needs to regenerate the thumbnail.
I don't know what dates Bridge is using to compare cached thumbs to images. I'd guess they are what we see as "Date File Modified".
I don't know where Bridge is getting those dates. Is Bridge getting the dates from the Operating System file management service? Has Bridge stored the thumbnail date in the cache index, and compares it to the image date? Because the regeneration comes and goes depending on the version of ACR, it would seem that Bridge is asking ACR for one of the dates.
All programs display dates in human readable form (Example: 7/15/2013 1:11:50PM). But dates are stored in some other form. I don't know what format is used, but it's probably some floating point format.
My theory is that the dates Bridge uses are in stored in different formats or different precisions of floating point. So, when Bridge compares two such dates they sometimes look unequal when in fact they are the same.
Different CPUs with different math chips might behave differently on critical floating point ops. This would explain why some users suffer the problem while others do not, even if they have the same version of OS.
My knowledge of floating point operations dates back to the IBM mainframes of the 70s. I have no idea how modern CPUs work. I'm hoping someone with current knowledge can comment on my theory. Also hoping the theory reaches Adobe techs, who currently appear to be stumped by this problem.

I found a folder of about 60 images, of which about 80% always repeated extractions, even if changing focus to another application for a couple of seconds.
If I batch-toggled Enable Lens Profile Corrections checkbox on every file in the folder, the repeat extractions stopped. If I toggled them back again, it started again.
This didn't surprise me too much, as the pre 7.3 bug, where repeat extractions occured when active Lens Profiles were combined with touching edge crops (fixed in 8.2), was also Lens Profile related.
Unfortunately, I couldn't isolate the combining factor which causes the repeats in combination with 80% of the files in that folder. Totally stumped.
As ssprengel suggests, it might be date/time-related. I did once notice some weirdness with file system timestamps in the Bridge cache folder. Maybe my 'bad' folder had files with a significant date/time.
Meanwhile, I now disable Lens Profile Corrections by default, which is the factory default setting. I only enable it on some shortlisted images. Repeat extractions a greatly reduced now. YMMV

HT2736 why am I getting a message suddenly that I am exceeding the gift card limit on my iTunes id for buying gift cards? I have never had a problem before and have a good credit card on file.

why am I getting a message suddenly that I am exceeding the gift card limit on my iTunes id for buying gift cards? I have never had a problem before and have a good credit card on file.

Interesting.
Didn't know Apple accepted PayPal as a payment option in some Stores. Cause they sure don't over here.

Get a SIM card from the carrier to whom the phone is legitimately locked.

Does anything show on your account's purchase history ? If you log into your account on your computer's iTunes via the Store > View Account menu option, you should then see a Purchase History section with a 'see all' link to the right of it. Click on that and you should then see a list of your purchases.
If it does and you didn't do the purchase(s), and nobody else has access to your account or devices, then try contacting iTunes Support via this page : http://www.apple.com/support/itunes/contact/ - click on Contact iTunes Store Support on the right-hand side of the page, then Purchases, Billing & Redemption. Is that how you tried contacting them ?
If it doesn't show on your account then contact your card issuer.
For your account being disabled have you tried getting it re-enabled ? If it's been disabled due to payments then you may need to contact support to get it enabled
