Description Andreas Kinzler 2012-07-16 16:06:39 UTC
Please see my mailing list post. Without a patch to completely disable HPET broadcast, you may experience an unstable system on xen 4.0/4.1.

Reproducible: Always

Is this fixed in 4.1.3 by any chance?
What was the result of your efforts to push this patch upstream?
Comment 3 Andreas Kinzler 2012-08-13 09:47:39 UTC
I don't think so. My patch is a workaround, not a bugfix. It disables all the HPET code, which as far as I know has never been fixed. But my research shows that you have to disable the buggy code for a stable system on non-ARAT CPUs (it is not used anyway on ARAT CPUs).

Andreas Kinzler, do you still have problem with xen's later versions? (4.2.4, 4.3.x)

and also I couldn't see any progress in xen upstream (eg, further discussion or with your patch accepted) ..
