Hi Konrad,
I just tried to boot a 3.8.0-rc0 kernel (last commit: 7313264b899bbf3988841296265a6e0e8a7b6521) as dom0 on my machine with current xen-unstable.
The boot stalls:
[ 0.000000] ACPI: PM-Timer IO Port: 0x808
[ 0.000000] ACPI: Local APIC address 0xfee00000
[ 0.000000] ACPI: LAPIC (acpi_id[0x01] lapic_id[0x00] enabled)

[ 0.000000] ACPI: LAPIC (acpi_id[0x06] lapic_id[0x05] enabled)
[ 0.000000] ACPI: IOAPIC (id[0x06] address[0xfec00000] gsi_base[0])
[ 0.000000] IOAPIC[0]: apic_id 6, version 33, address 0xfec00000, GSI 0-23
[ 0.000000] ACPI: IOAPIC (id[0x07] address[0xfec20000] gsi_base[24])
[ 0.000000] IOAPIC[1]: apic_id 7, version 33, address 0xfec20000, GSI 24-
[ 64.598628] INFO: rcu_preempt detected stalls on CPUs/tasks:
[ 64.598676] 0: (1 GPs behind) idle=aed/140000000000000/0 drain=5 . timer not pending
[ 64.598683] (detected by 1, t=18004 jiffies, g=18446744073709551414, c=18446744073709551413, q=162)
[ 64.598692] sending NMI to all CPUs:
[ 64.598716] xen: vector 0x2 is not implemented
Perhaps an interesting line is the incomplete (no end of range, and it stalls there some time before the kernel reports the stall itself:
[ 0.000000] IOAPIC[1]: apic_id 7, version 33, address 0xfec20000, GSI 24-
The exact seem config with 3.7.0 as kernel works fine.
Complete serial log is attached.

Yeah, saw it over the Dec 11->Dec 12 merges and was out on
vacation during that time (just got back).
Did you by any chance try to do a git bisect to narrow down
which merge it was?
Thanks!

Hi Konrad,
Nope haven't had the time, I only tried resetting to commit 189251705649bdfdf5e5850eb178f8cbfdac5480 as a "hunch"(just before a lot of x86 and rcu commits), but the result didn't boot ..

Hi Konrad,
I tried to bisect, but did not succeed so far. But somehow i have the feeling it is at least partly .config related.
After make a new clone, and by hand trying to bisecting down, i came back to v3.7, but that also didn't boot.
So i will see if i can do it the other way around :S

30106c174311b8cfaaa3186c7f6f9c36c62d17da is the first bad commit
commit 30106c174311b8cfaaa3186c7f6f9c36c62d17da
Author: Fenghua Yu <fenghua.yu@intel.com>
Date: Tue Nov 13 11:32:41 2012 -0800
x86, hotplug: Support functions for CPU0 online/offline
Add smp_store_boot_cpu_info() to store cpu info for BSP during boot time.
Now smp_store_cpu_info() stores cpu info for bringing up BSP or AP after
it's offline.
Continue to online CPU0 in native_cpu_up().
Continue to offline CPU0 in native_cpu_disable().

Hey Sander,
Thank you for doing the bisection.
Fenghua - any ideas what might be amiss in the Xen subsystem?
I hadn't looked at the patchset of the CPU0 offlining/onlining
so I am not completly up to speed on the particulars of the patches.

be able to test this and look in more details tomorrow.
