Kernel panic sometime after 10.4.9 software-updated, SMB?

Question

Apparently samba-networking related - makes sense: it happened as I saved a BBEdit file to an already-SMB-mounted Window2000 server volume (across wired ethernet). Earlier I'd rebooted a couple of times after the update (once then it asked me to, a second time to check everything was OK).

Answer 1

Then, I suspect your permissions are a bit out of sorts. Launch Disk Utility and repair the permissions and try downloading again. If still no go, create a new admin user account, log into it, and try downloading. If that's successful, then the problem lies within the old account, most likely a conflicting or corrupted preference file, and you'll have to sort that out.
