Some kind of hint? Greg, Konrad is referring to: commit 73d63d038ee9f769f5e5b46792d227fe20e442c5 Author: Suresh Siddha Date: Mon Mar 12 11:36:33 2012 -0700 x86/ioapic: Add register level checks to detect bogus io-apic entries With out this commit, if the bios lists bogus io-apic's, then we will see some error messages ("Unable to reset IRR for apic")during linux boot which are benign. But as this patch breaks Xen, I am ok if these don't get applied to 'stable'. Also I think it is Ingo who added the 'stable' tag. Ingo, are you ok with this? For the mainline, we have queued more patches to fix the Xen breakage. thanks, suresh > > And note, you forgot to send this to the stable@vger.kernel.org list, > where the other stable kernel maintainers live, please do so next time. > > thanks, > > greg k-h
