RE: [Xen-devel] timer_interrupt problem

["Guy Zana" <guy@xxxxxxxxxxxx>]

Yep. It's a Dual Core T60 (VT is enabled).

The APIC error is really after dom0 starts to run, the error appears after the message about relinquishing the console.

 

The problems didn't appear in changeset 13090 of the unstable tree (non PAE mode).

 

1. Can it be related to PAE? (hard to see how)

2. Can I use the old kernel (2.6.16.33) with changeset 13568? I didn't have much problems with that version of the kernel, although I don't want to mess with inconsistencies...

 

Should I check the latest changeset?

 

Guy.

Is it a dual core T60? The APIC errors are concerning ? that particular error (illegal vector) is most often a sign of bad hardware. If it?s a UP laptop then you might try booting with ?nolapic noapic nosmp? as a set of extra Xen boot parameters. If it?s SMP then the APIC errors are harder to explain away.

Do you know when during boot the APIC errors appear (e.g., before or after dom0 starts to run)?
