Lockup with 2.6.12-rc5

[Adam Lackorzynski <adam@os.inf.tu-dresden.de>]

Hi,

I've been experiencing lookups of a quite heavily used file server.
These lockups happen after some days, and I've also seen them with
2.6.11 based kernels. Kernels of the 2.6.8 series are running fine for
weeks.

The box is a dual Xeon (HT wasn't detected), network uses acenic and discs
sym53c8xx.
