^^^^^^^^^^^^^^^^^^^^^

Something somewhere has trampled over kernel data structures,
resulting in a corrupted block device request queue.
Odds are very good that any block device drivers will trap
from that point onwards; the ide driver just "got lucky" in
this case, but was not the culprit.

Finding the culprit is darned near impossible in this situation.
