Description Eduardo Habkost 2007-09-17 16:44:11 UTC 
This bug is for the tg3 synchronize_irq() warnings reported initially on bug 
#252301.

Stability problems reported on bug #252301 were fixed. This bug is for the tg3 
synchronize_irq() warnings that remained on kernel-xen 2.6.21-2937.fc8 and 
later.


+++ This bug was initially created as a clone of Bug #252301 +++

Description of problem:
I've updated to 2.6.21-2925.15.fc8 from 2.6.21-2925.14.fc8 and some things get
broken.
- Xserver restarts sometimes
- installation of RHEL4 fullvirt machine results in kernel faults (rhel4 guest
kernel fail)

Version-Release number of selected component (if applicable):
2.6.21-2925.15.fc8

How reproducible:
always

Do you have the remaining of the dmesg contents? Especially the ACPI and 
IRQ-related messages.

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 
synchronize_irq() warning.

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 
related
to this

Thanks.
I will create a separated bug for the tg3 synchronize_irq() warning.
Comment 1 Michael Carney 2007-09-29 14:52:08 UTC 
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:

Any ETA when the fix will show up in F7?

Thanks.

Built new F-7 package including fix for the warning. 
http://koji.fedoraproject.org/koji/taskinfo?taskID=189649

This should go to the next F-7 update.

A package including the fix was submitted to Rawhide, also 
(kernel-xen-2.6-2.6.21-2949.fc8)

There are no more synchronize_irq messages being generated when
2.6-2.6.20-2943.fc7 is used. Thanks.
