Hi,
I've been trying to upgrade kernel from 2.6.12.3 to 2.6.13-rc4 on a
rather loaded http server, but i'm currently having a kernel panic a few
minutes only after booting. The bug was reproductible (the crash
happened after every reboot, with the same backtrace).
Here is the error log:
------------[ cut here ]------------
