I think detailed output of dmesg (both xen and dom0) will be helpful. I checked the log again, and noticed following output. Seems there is IRQ source override for timer in the platform and dom0/xen have different idea of timer source in check_timer(). >> (XEN) ioapic_guest_write: apic=0, pin=2, old_irq=0, new_irq=-1 >> (XEN) ioapic_guest_write: old_entry=000009f0, new_entry=00010900 >> (XEN) ioapic_guest_write: Attempt to remove IO-APIC pin of in-use IRQ! >> (XEN) ioapic_guest_write: apic=0, pin=4, old_irq=4, new_irq=-1 >> (XEN) ioapic_guest_write: old_entry=000009f1, new_entry=00010900 >> (XEN) ioapic_guest_write: Attempt to remove IO-APIC pin of in-use IRQ! >> (XEN) ioapic_guest_write: apic=0, pin=0, old_irq=-1, new_irq=0 >> (XEN) ioapic_guest_write: old_entry=00010900, new_entry=000009f0 Thanks Yunhong Jiang >-----Original Message----- >From: Patrick Colp [mailto:Patrick.Colp@xxxxxxxxxx] >Sent: 2009年6月26日 17:38 >To: Jiang, Yunhong >Cc: Christian Tramnitz; xen-devel@xxxxxxxxxxxxxxxxxxx >Subject: Re: [Xen-devel] Re: Xen cannot boot with pvops dom0 > >I tried reverting those two changesets with no real effect (I >got an extra error >message from Xen to do with something about the timer). > >I still have a sneaking suspicion the problem is with the >Linux kernel and not >Xen, but I could be wrong. > > >Patrick > > >Jiang, Yunhong wrote: >> hi, all, can you try to revert following two patches to see >if any help? >> If it do fix the issue, I will look it tomorrow when back to office. >> >> --jyh >> >> >> changeset: 19809:16c2806b09c6 >> user: Keir Fraser <keir.fraser@xxxxxxxxxx> >> date: Tue Jun 23 11:11:46 2009 +0100 >> files: xen/arch/x86/irq.c >> description: >> x86: Another assign_irq_vector() cleanup. >> >> Signed-off-by: Yunhong Jiang <yunhong.jiang@xxxxxxxxx> >> >> >> changeset: 19804:07fea69baadc >> user: Keir Fraser <keir.fraser@xxxxxxxxxx> >> date: Fri Jun 19 08:43:58 2009 +0100 >> files: xen/arch/x86/irq.c >> description: >> x86: Fix legacy irq allocation issue >> >> When try to assign vector for irq, we should not assign vector for >> legacy irq, which has fixed mapped irq<->vector relationship. >> >> Signed-off-by: Jiang, Yunhong <yunhong.jiang@xxxxxxxxx> >>> -----Original Message----- >>> From: xen-devel-bounces@xxxxxxxxxxxxxxxxxxx >>> [mailto:xen-devel-bounces@xxxxxxxxxxxxxxxxxxx] On Behalf Of >>> Christian Tramnitz >>> Sent: 2009年6月25日 20:09 >>> To: xen-devel@xxxxxxxxxxxxxxxxxxx >>> Subject: [Xen-devel] Re: Xen cannot boot with pvops dom0 >>> >>> Patrick Colp wrote: >>>>> I found the boot issue on my Q35, it can boot on my Nehalem. >>>> What are the motherboard chipsets? >>> Q35 *is* the chipset, for Nehalem its a Tylersburg chipset >(either X58 >>> or 55x0) >>> >>> Best regards, >>> Christian >>> >>> >>> _______________________________________________ >>> Xen-devel mailing list >>> Xen-devel@xxxxxxxxxxxxxxxxxxx >>> http://lists.xensource.com/xen-devel >>> >> >> >> >--------------------------------------------------------------- >--------- >> >> _______________________________________________ >> Xen-devel mailing list >> Xen-devel@xxxxxxxxxxxxxxxxxxx >> http://lists.xensource.com/xen-devel > _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
