Default Bug#484593: linux-image-2.6.25-2-686: su gets stuck for root -- stty getting stuck in T state

Package: linux-image-2.6.25-2-686
Version: 2.6.25-4
Severity: normal

There's an upstream bug that has started affecting me. stty gets
backgrounded, and you can only kill -9 it to get your shell back. A
thread titled "su gets stuck for root" is on LKML with all the
details, and when there's an eventual patch, it would be good to
include it in the debian patchset.

-- Package-specific info:

Does this error still occur with the Lenny kernel?

It did last time I used that machine, but it's since been decomissioned.
Since this is a race condition that obviously depends strongly on timing
(it was quite a slow machine), I'm not going to say the bug is gone.
There was no more activity on that "su gets stuck for root" thread on
LKML, so I doubt it's been deliberately fixed.
