I had a similar problem which has been solved by plugging
in a PS/2 mouse. So far I've got about 10 reports from people where
the PS/2 mouse solved the problem. It seems it is limited only to
the revision 04 of AMD 768 southbridge, and especially the MSI K7D-Master
boards. My lspci looks like this:
00:00.0 Host bridge: Advanced Micro Devices [AMD] AMD-760 MP [IGD4-2P] System Controller (rev 11)
00:01.0 PCI bridge: Advanced Micro Devices [AMD] AMD-760 MP [IGD4-2P] AGP Bridge00:07.0 ISA bridge: Advanced Micro Devices [AMD] AMD-768 [Opus] ISA (rev 04)
00:07.1 IDE interface: Advanced Micro Devices [AMD] AMD-768 [Opus] IDE (rev 04)
[...]
It is even somewhat documented as an official AMD erratum.
This is not a dead-lock per se - but rather a hard lock-up
of the box (the system is totally locked up, even pressing NumLock does
not light the NumLock LED on the keyboard).
However: I also have occasional (less than 1 per week) dead-locks
on this box related probably to NFS or ext3 or NFS-lockd - the system is
OK, only all nfsd and lockd processes are stuck in the "D" state,
sometimes there is also an "exportfs -a" process in the "D" state
(my /etc/exports is generated from database, and I run exportfs
every two hours or so). And I think it is SMP-related, not necessarily
AMD-related. These deadlocks are more often in 2.4.21-pre kernels
than in vanilla 2.4.20. See my previous posts to LKML on this topic as well.
