Description of problem:
Kernel panic occured overnight, probably at around 12am. Kernel oops
output (see http://www.sgc.ox.ac.uk/aetherpanic.JPG ) suggests it was
triggered by logwatch.
The machine is fully up2date as of early last week.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
Actual Results: Kernel panic
Expected Results: No kernel panic
ncpfs is compiled as a kernel and was loaded. It was used to mount a
remote Novell filesystem.
The loopback device was in use mounting an ISO image.
Hello, Brian. The ncpfs module is unsupported, and it could
be the source of the problem that later led to the oops in
__free_pages_ok(). Could you please try to reproduce this
problem without ncpfs?
In the meantime, I'll assign this tentatively to someone
familiar with our VM subsystem.
I suspect most of the new problems with ncpfs is because of SELinux. I
had to switch it off on my machines running FC3. I got this:
SELinux: initializedc(dev ncpfs, type ncpfs), not configured for labeling
Also got a whole bunch of:
ncpfs: Connection invalid!
