Unexpected IRQ trap at vector dd
Last modified: 2008-04-28 22:01:35 EDT
Description of problem:
After the last hibernate/thaw cycle, the system became very slow and I'm getting
some weird messages in dmesg.
Version-Release number of selected component (if applicable):
Seen once so far. Next hibernate/thaw cycle returned the machine into the same
Steps to Reproduce:
1. Hibernate Dell Inspiron 6400.
Becomes slow, dmesg filled with unhealthy messages.
Worked fine before
Will attach usual suspects.

That's weird. It's like MSI got enabled for some device by accident.
Can you try booting with kernel option "pci=nomsi" and try to reproduce?
That's the thing - I can't reproduce it at will at all. It happened once so far
and this machine must have been hibernated/thawed tens of times with this kernel
before it happened. After that latest reboot (caused by this problem) I must
have had at least 10 cycles - nothing. I also have another Dell Inspiron 6400
which is being hibernated/thawed regularly and never observed this problem at all.
You still want me to try this option?

I don't know how we'd be able to tell if it works...
Yeah, that's what I was afraid of. Close it with COSMICRAYSFLIPPEDBITS? :-)
