cpu error 4 (was: Re: O2 framebuffer problems with install kernel)

[Jorge Acereda Maciá <jacereda%gmail.com@localhost>]

Hi,

With the first patch (the one using BUS_DMA_COHERENT), I get constant  
reboots, usually under heavy IO load (probably an unrelated problem).

For instance, I've been so far unable to complete a:

cd /usr/src
cvs -z3 update -d -P

I've also noticed messages like this printed occasionally:

crime: cpu error 4 at address 4c38444

The address varies.

Should I suspect of faulty hardware? I think this machine was being  
used in production until recently...

Thanks,
  Jorge
