Re: [Xen-devel] cpuidle and un-eoid interrupts at the local apic

Next crash occured, debugging output included.

One Remark: Over the last days (besides many linux PV guests) 1 Windows Guest (with PV drivers) was running, today I've started another Windows guest and during 3 hours two crashed occured, coincidence ?

Best regards
  Thimo

All of these crashes are coming out of mwait_idle, so the cpu in
question has literally just been in an lower power state.

I am wondering whether there is some caching issue where an update to
the Pending EOI stack pointer got "lost", but this seems like a little
too specific to be reasonably explained as a caching issue.

A new debugging patch is on its way (Sorry - it has been a very busy few
days)
