@Stefan, One interesting thing is we are seeing the crashes on m1.larges of a certain server type, but that same type running on m2.xlarge has not seen any crashes. Seeing same network and IO patterns in both cases but no crashes on the larger instance type.
I disabled irqbalancer on one group of servers that appear to have given that class some stability there, although I can't say definitely since I was never able to reproduce the issue but it's been a couple of weeks since we've seen a kernel panic on them since disabling irqbalance. Is there any other debug information I can attempt to gather? I'm also testing Kernel 3.2 from mainline on a server w/ irqbalance enabled to see if that makes a difference. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1178707 Title: Kernel Panics - ec2 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1178707/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
