Re: vanilla 2.5.13 severe file system corruption experienced

[Anton Altaparmakov]

The IDE core has a nasty PIO bug which causes it to scribble randomly over 
your disk (even when read-only mounted or not mounted at all).

Wait for 2.5.14, that has the fix in it, or use the latest -dj kernel which 
has the fix, too.

Note even with that fix IDE (at least TCQ) is really easy to crash when you 
put the system under heavier I/O (at least on my via box)...
