Description Marc Dequ 2006-01-09 04:06:28 UTC
Distribution: Debian GNU/Linux (testing)


Problem Description:

Filling /home with ISOs got an Oops when reaching the last 4-5% free space
available (last report from stats before they die). Then all processes using any
XFS partition hung, and softirqs brought CPU usage to 100%. Other (few)
softwares were still working nicely. After a necessary reboot, no corruption on
the fs was found.
