Description of problem:
I'm having kernel oopses on the aacraid on FC2 starting with
kernel-2.6.8. All 2.6.8 kernels were really unstable (most times I
couldn't get past the init scripts during server bootup). Upon release
of 2.6.9-1.3_FC2smp, I tried it and it seemed to solve the problem,
until today (2 weeks uptime) and I got the same oops again.
The problem reported is that a sleeping function was called from an
invalid context on mm/slab.c, and the backtrace reports functions of
My RAID controler is a Adaptec AIC7902 Ultra320 SCSI, 2200S, kernel
7244. The server is a dual Xeon with HT enabled. Find attached a dmesg
output I managed to retrieve when this problem occurred while I was
logged from another machine (while I was using 2.6.8). I haven't tried
kernels 2.6.6 and 2.6.7, but 2.6.5 seems stable as a rock (3 months
uptime without any problem).
Version-Release number of selected component (if applicable):
kernel-2.6.8 and kernel-2.6.9
Steps to Reproduce:
1. Boot with kernel 2.6.8 or 2.6.9.
2. Wait for a system crash.

dmesg output (with oops backtrace)
While the oops sounds different, this might be a duplicate of bug
#129529 - the timeline sounds about right for the problems being
experienced in that report.
Fedora Core 2 has now reached end of life, and no further updates will be
provided by Red Hat. The Fedora legacy project will be producing further kernel
updates for security problems only.
If this bug has not been fixed in the latest Fedora Core 2 update kernel, please
try to reproduce it under Fedora Core 3, and reopen if necessary, changing the
product version accordingly.
