Yes, I've seen this from time-to-time as well, although I've never been able to reproduce it either. It hits the BUG() in io_apic.c:127 basically when it thinks we are trying to remove a irq_2_pin mapping that wasn't added in the first place. I don't have much more than this at the moment.

I'm sorry nobody has looked at this in a while. Is this still a problem with recent RHEL-5.4 Xen? I haven't seen it in over a year myself, so I'm just wondering if you still see the problem. Thanks, Chris Lalancette
No response in over a month, and I haven't seen this myself in a long time. I'm going to close this as CURRENTRELEASE for now; if it pops back up, feel free to re-open. Chris Lalancette
