I could rebuild the 2.6.26 host and guest kernels for the system in

PATA card to boost disk from ATA/33 to ATA/133).
If you don't think the hardware changes will skew the results, I can
temporarily downgrade the kernels, apply the patch (to 2.6.26,
regrettably I no longer have Debian's 2.6.28 sources available), and try
to reproduce the problem.
Please apply this patch to 2.6.26. We want to fix the bug in lenny
(2.6.26) and we don't care about .28 any more. I don't think this is
hardware-dependent, so don't bother changing your hardware back.
Ben.
Today, I started playing around with unpatched .26 kernels as host and
guest on my server. Regrettably, I am yet to reproduce the bug,
although the system *feels* a lot slower with .26 as host _and_ guest.
I may yet try booting with the IDE in PIO mode, to artificially degrade
CPU and disk performance, and see what happens.
On a different note, I applied your patch to my desktop machine (still
running 2.6.26, despite being a mix of testing/unstable/experimental) a
few weeks ago, in an attempt to improve OpenOffice.org performance.
Since doing that, I have been noticing X freezing (mouse moves, but no
hot-tracking, and unable to switch tasks or VT's) when OOo, or another
application, is busy. Usually, when OOo is busy, I will switch to
another task (or IceWeasel ;-) and continue working.
I'll give more feedback if and when I manage to tickle the bug on my server.
Cheers,
Brendon Green
