Indeed. This strengthens my presumption that Xen has a severe problem on
this platform (that is Intel 3420 [Ibex Peak] and 1156 "Lynnfield" CPUs).

Uptime is now 160 hours with this patch on my machine.
Is this confirmed, or just your experience so far? We also use
SuperMicro and I was about to get a new Lynnfield CPU system, but
don't want to sit with problematic hardware.

I am working on tests to confirm that and I contacted the developers.
Right now uptime is over 8 days.

If my presumption is correct, then you need to understand that it is not a problem of Supermicro. In a 2 month testing process I changed the mainboard and used one from ASUS and the problems were absolutely the same. The problem seems to be between Xen and the platform (not the mainboard maker).

I am starting tests with Supermicro X8DTi and E5620 very soon. Since this platform has ARAT (always running APIC timer) I expect a working platform.

As matter of interest, how do you check the Motherboard mak
