[Bug 69430] ext3 filesystem corruption?

[rsidd]

Public bug reported:

Binary package hint: linux-image-2.6-amd64-generic

This is a Sun Ultra20 (dual-core AMD opteron) machine, on which I installed Dapper on August 2, kernel
vmlinuz-2.6.15-23-amd64-generic
It had been up from then until October 28, no reboots, no shutdowns (unclean or otherwise).   Then I ran update-manager -c to upgrade to edgy.  The upgrade appeared to go through successfully, and it asked me to restart the computer.  On restarting, there seemed to be extensive problems in the /usr (ext3) filesystem.  The other filesystems, including /home (xfs), seem fine.  (These are the two largest filesystems, over 100 GB each.)

So far I haven't noticed any problems after the manual fsck of /usr.
