After updating kernel and ZFS modules, system cannot boot

Starting Import ZFS pools by cache file...
[ 4.966034] VERIFY3(0 == zap_lookup(ddt->ddt_os, ddt->ddt_spa->spa_ddt_stat_object, name, sizeof (uint64_t), sizeof (ddt_histogram_t) / sizeof (uint64_t), &hht->ddt_histogram[type][class])) failed (0 == 6)
[ 4.966100] PANIC at ddt.c:124:ddt_object_load()
[*** ] A start job is running for Import ZFS pools by cache (Xmin Ys / no limit)
And then occasionally I see
[ 240.576219] Tainted: P O 3.19.2-1-ARCH #1
Anyone else experiencing the same?

Thanks!
I did the same and it worked... kind of. The first three reboots it failed (but did not stop the system from booting) producing:
zpool[426]: cannot import 'data': one or more devices is currently unavailable
systemd[1]: zfs-import-cache.service: main process exited, code=exited, status=1/FAILURE
The second boot also resulted in a kernel panic, but as far as I can tell unrelated to zfs.
After reboot one and three imported the pool manually.
From the fourth reboot on loading from cache file always succeeded. However, I it takes faily long (~8 seconds) and even shows
[*** ] A start job is running for Import ZFS pools by cache (Xmin Ys / no limit)
briefly. Altough I might only notice that because the recent updates sped up oder parts of the boot process. Did you observe a slowdown during boot time, too, kinghajj?

  • Exception processing message 0xc0000013 after updating itunes and Quicktime

    After updating itunes and Quicktime, every time I remove a CD from my DVD drives I get an error saying no disk exception processing message 0xc0000013 Parameters 0x759f023c 0x87f51934 0x759f023c 0x759f023c.

    Any help would be greatly appreciated.

    I also have the same problems as you guys after installing Corel Painshop Pro X12. I went into the task list and stop the CorelIOMonitor process and then the problem went away. I found out that you can disable this from starting up using System Configuration tool via Start -> Run -> msconfig
    . It's an interm solution untell they fix it. Maybe someone needs to notify Corel or Apple to fix this problem.

  • After updating numbers and pages I can no longer copy multiple cells from numbers and paste and match style to pages.

    After updating numbers and pages I can no longer copy multiple cells from numbers and paste and match style to pages.  I used to be able to select multipule cells in a row (such as company name, address, etc.) then paste and match style on to a pages letter. I found the paste and match style option in the edit menu, however it will only work one cell at a time. Before the update is was working great.

    For diagnosing purpose thy the procedure in a new user account and see if it works there. You create a new user account in the System Preferences > Accounts. If it works in the new account it is probably a corrupt plist file that needs to be deleted.

    Send a bug report. And wait for an update.
    OR
    uninstall and re-instal the game all over.

    All the monitoring is done through your sound device, not Audition. When you updated your PC, the sound device playback settings would have been reset. One of them includes input socket monitoring, and it's this that you need to reinstate. Since we don't know what sound device you are using, that's as much as we can tell you, except that if it's an internal device, you'll need to open the volume control options and alter it there. This varies between OS versions though...

    Hi,
    Can you test in another computer?
    It seems this is related to your installation media. If so, it is recommended to try a good copy.

    If you restore from iCloud backup the apps will be automatically downloaded. If you restore from iTunes backup the apps and music have to be in the iTunes library since synced media like apps and music are not included in the backup of the iOS device that iTunes makes.

  • After updating my IOS to 6, I cannot get my phone to shut off and stay off.  I turn it off and it comes right back on.  Is anyone else having this problem?

    After updating my Iphone 4S to the newest operating system, I cannot get my phone to stay off when I turn it off.  Has anybody got any ideas what to do?

    Hello purplechemist,
    I would be concerned too if my iPhone was not turning off.  I'm not sure if you have tried this, but I recommend first trying to reset your iPhone:
    Resetting your device
    Press and hold the Sleep/Wake button and the Home button together for at least ten seconds, until the Apple logo appears.
    You can find the full article here:
    iPhone, iPad, iPod touch: Turning off and on (restarting) and resetting
    http://support.apple.com/kb/HT1430
    If the issue persists after the reset, I recommend restoring your iPhone.  You can find steps for backing up and restoring your iPhone in the following links:
    iOS: How to back up
    http://support.apple.com/kb/HT1766
    iTunes: Restoring iOS software

    Thank you for posting in the Apple Support Communities.
    Best,
