2.0.32 IDE-related crash

[Olaf Titz]

Saw this one for the first time yesterday. The affected disk was a
news spool. (Which gave a lot of errors in the past, apparently due to 
the high load, but the disk has been replaced since.) After the stuff
below appeared in the syslog, everything trying to access hdc hung in
D state and eventually no new processes could be spawned.
