Description Bojan Smojver 2008-04-27 04:10:19 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):

How reproducible:
Seen once so far. Next hibernate/thaw cycle returned the machine into the same
slow state.

Steps to Reproduce:
1. Hibernate Dell Inspiron 6400.
2. Thaw.
Actual results:
Becomes slow, dmesg filled with unhealthy messages.

Expected results:
Worked fine before

Additional info:
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?
Comment 6 Bojan Smojver 2008-04-27 23:49:49 EDT
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...
Comment 8 Bojan Smojver 2008-04-28 22:01:35 EDT
Yeah, that's what I was afraid of. Close it with COSMICRAYSFLIPPEDBITS? :-)
