Hi Chris,
How easy is this to reproduce? Is this immediate or under load?
How much memory does the host machine have? How much allocated to the
domain?
And to be clear, this is plain 2.6.25, not 2.6.25+mergewindow, right?
(BTW, it would help if you cc: me on Xen bug reports, since I don't
necessarily catch up on lkml traffic very quickly.)
Thanks,
J

Whoops. Been on holiday for the past few days.
>> How easy is this to reproduce? Is this immediate or under load?
I'm not sure what the VM was doing when this was hit. I'll open 2.6.25
up for more testing and see what happens...

24G on the host server. 300M allocated to dom0 and 360MB to domUs.
>> And to be clear, this is plain 2.6.25, not 2.6.25+mergewindow, right?
Correct -- no extra patches.

Not a problem (so many lists...)
