Description Ed Marshall 2007-03-04 17:48:28 UTC
Description of problem:
Kernel panic'd overnight, leaving automounts in a hung state.

Version-Release number of selected component (if applicable):
2.6.19-1.2911.6.4.fc6

How reproducible:
Not at all; this happened randomly in the middle of the night. autofs appeared
to be hung afterward, as the system couldn't shut down without a hard reset, and
all mounts were hanging.

Additional info:
We've had occasional freezing with this machine since moving to autofs-mounted
home directories. This is the first time we've had a panic reported. I've
attached the relevant snippet of /var/log/messages.

Comment 3 Ed Marshall 2008-04-04 12:15:45 UTC
The problem appears to have been resolved since moving from Fedora 6 to 8. (We
were on 7 only long enough to complete the upgrade to 8, so I can't say whether
a change in 7 resolved it. If anyone is curious, the server tracked Fedora
releases pretty closely, and so was running 7 and 8 shortly after their release.)

Our interim resolution to the problem, which wouldn't be acceptable to most, was
a nightly automated reboot of the problematic machine, which headed off the
issue most of the time. Since moving to 8, we've found it unnecessary to do so.
