Re: [Xen-devel] xen-2.0 20040910 problems
Actually, it IS an sis900. 8-P I didn't even stop to think of looking
for the module with the error message. *thwaps self*
In past kernels, the sis900 driver has behaved correctly. I DO have
writeable page tables enabled though.
The server was sitting idle at the time of the problem triggering each
time. So I don't think it was a load issue....
Could you point me to the location you found that path at? I'll do a bit
of debugging with it as a moduel to see if I can't figure it out...
