Hi, 

I'm afraid I've found a way to panic the ALPHA-pl11 kernel pretty 
consistantly!

If you use mtools and mdir a 720K dos disk (when you thought it was a 1.44M
one!) and then wait for a bit, it'll say 

floppy 0: sector not found: track 0, head 0, sector 1

about 5 or 6 times then

Floppy I/O error
dev 021c, sector 0

and that's yer lot...

"Unable to handle kernel paging request at address c0000070..."

Looking further, I find EIP is 0010:00054A2B which in my build is in
end_request, and is the assembler code 

movl (%eax,%edx,4),%eax

which equates to the line

req->sector += (BLOCK_SIZE / 512);

Now I can't see how this would blow up the kernel unless the value of req
was being changed while the function wasn't looking?

Any offers?

Phil

help (sigh...)
