once again, it's *pprev=next which is is causing trouble, with pprev=6 this
time (fs/buffer.c:523). There really seems to be something playing badly with
this...

I find amazing that such widely used portions of code only trigger panics on
your system ! either it's a rare combinations of several components/drivers, or
a strange hardware problem, although I can't imagine which (cpu? bus locking?).

Cheers,
