Do you have the remaining of the dmesg contents? Especially the ACPI and
Is the TG3 network interface working, even with the warnings?
If you have the full contents of dmesg and 'xm dmesg' of both
2.6.21-2925.14.fc8 and 2.6.21-2925.15.fc8, they will be useful for checking
what changed from one version to another.

A new kernel-xen was submitted including a fix on the kernel IRQ handling.
This may help to solve some of the issues, especially the TG3
Could you test kernel-xen-2.6-2.6.21-2931.fc8 (that is building right now and
should go to Rawhide soon) and report if the problems remain?

I tried 2.6.21-2940.fc8 and it looks fine. Kernel has no problems under heavy
load. Only tg3 issue will be seen in dmesg output but I have no problems

I will create a separated bug for the tg3 synchronize_irq() warning.
I've experienced this annoying bug (synchronize_irq) since after 2.6.20-2925.13
on F7. It's still in 2.6.20-2936.fc7, filling up /var/log with:
BUG: at kernel/irq/manage.c:33 synchronize_irq()
[<cf1cb5ab>] vortex_timer+0x65/0x39d [3c59x]
Any ETA when the fix will show up in F7?

*** Bug 321001 has been marked as a duplicate of this bug. ***
Built new F-7 package including fix for the warning.
This should go to the next F-7 update.
A package including the fix was submitted to Rawhide, also
kernel-xen-2.6-2.6.20-2943.fc7 has been pushed to the Fedora 7 testing repository. If problems still persist, please make note of it in this bug report.
If you want to test the update, you can install it with
su -c 'yum --enablerepo=updates-testing update kernel-xen-2.6'
kernel-xen-2.6-2.6.20-2943.fc7 has been pushed to the Fedora 7 stable repository. If problems still persist, please make note of it in this bug report.
There are no more synchronize_irq messages being generated when
2.6-2.6.20-2943.fc7 is used. Thanks.
