Crashme test

Crashme test

[Pedro Gracia]

Hi all,

I'm using Xen in a desktop enviroment with debian and fdl for about six 
weeks and finally, after a lot of weeks with continuous resets (instant 
shutdowns) while I'm using firefox in my debian dom0 and the same resets 
with a conexant usb modem (while the modem is starting the beeps for the 
call), I found a test that reset my Xen box in less of 1 second...

ii  crashme        2.4-5          Stress tests operating system stability

My box pass the crashme test with a normal 2.6.11.8 kernel for a few 
minutes (I didn't to use crashme for an hour).

Someone can test this? I'm using Xen 2.0.6 (stable) but I had the same 
resets with an Xen-unstable too.

Thanks a lot,

Pedro

Yep, I can reproduce this using 'crashme +2000 666 100 1:00:00' with the
binary at http://www.cl.cam.ac.uk/~iap10/temp/crashme

It happens in domU as well as dom0, which should make it easier to debug
as the test cycle is quicker.

The crashme problem should now be resolved in testing and unstable.

It would be helpful if more people give Xen some more stress with crashme
just to be sure.
