This is precisely the same as the error I reported a couple of weeks
back (Toshiba Satellite 4100 XDVD, 2.3.99-pre7).

Your 'struct poll_table' in __poll_wait() is getting 0xffffffff written
all over it.

For me, this was associated with IDE DMA timeouts.

Are you using IDE DMA? Have you tried turning it off? (hdparm -d 0

I also observed 4k lumps of 0xff getting written into NFS-served files.
It makes me think that _something_, probably in the IDE code is spraying
blocks of 0xff into places where it shouldn't.
