Just got another one :-(
I've turned off ATA write cache and ATA DMA now. Seems to help a bit,
but in half a hour I had it crashing again.
Dammnit. What's going on here :-(((
And what I really really hate is that a normal buildworld
doesn't trigger it. Just a openoffice build. F***.
panic: bwrite: buffer is not busy???
