Hi, I was testing kernel 3.2.10-2 from koji. After using the machine for a while one suddenly gets messages saying certain irq's are disabled. At the point the system slows down to a crawl. Restarting X etc does not change anything. Reboot fixes the problem. It happened all two different machines. Both are DELL T5500's. One with a quad CPU the other dual six-core cpu's. I don't think 3.2.10-1 was doing this. FYI
There was a bad patch included in 3.2.10-2. Could you try this kernel here: http://koji.fedoraproject.org/koji/taskinfo?taskID=3898618
OK. I am trying so far so good. But the IRQ messages came after a few hours of working. I am not sure what triggers it to suddenly decide to eliminate some irq's, but in the past these messages did not effect the system performance.

Can you post the full dmesg from that kernel boot as well?
Sorry about the repost....I am attaching the segment from the messages file for the last reboot. I am not getting dmesg files in Fedora 16 anymore but just boot,log and messages!
Created attachment 570674 [details] messages for last reboot
I see that kernel 3.2.10-3 have been pushed to updates. Does this contain the fix? Thanks

Thanks It drops the broken patch that was in 3.2.10-2, so yes 3.2.10-3 should fix the issue you were seeing. The next kernel update submitted after that will have a fixed version of the patch that is found in the 2.2 kernel you are testing.
