Description W. Michael Petullo 2010-10-11 22:46:48 EDT
Description of problem:
Xen is not booting on a system with an ASUS A8N-E motherboard. The boot process seems to fail before Dom0 is loaded.

Version-Release number of selected component (if applicable):
Xen 4.0.1

How reproducible:
Every time

Steps to Reproduce:
1. Install Xen and a Dom0 kernel on a system with an A8N-E motherboard
2. Boot the system
Actual results:
Boot process fails with "IO-APIC + timer doesn't work!" Booting with "noacpi numcpus=0" allows the system to boot but results in an unstable Dom0 kernel.

Expected results:
The system should boot.

Which xen package version did you see this with? There were some changes between xen-4.0.1-1.fc14 and xen-4.0.1-4.fc14 that might have had affect this issue (don't use xen-4.0.1-3.fc14).
Comment 3 W. Michael Petullo 2010-10-12 12:04:48 EDT
The package I have been using is xen-4.0.1-4.fc14.x86_64.
Comment 4 W. Michael Petullo 2010-10-12 12:14:42 EDT
I also tried xen-4.0.1-1.fc14.x86_64 and that package had the same problem.
Comment 5 Michael Young 2010-10-12 12:31:26 EDT
It looks like a known upstream bug, see
It looks like a patch for it is in the test queue for 4.0.x
but not yet in the "will be in the next 4.0.x" queue
Comment 6 W. Michael Petullo 2010-10-12 13:13:38 EDT
The patch at fixes the problem. Could we add this patch to the Fedora package until it is upstream?
