Description Andrew Zabolotny 2007-06-29 16:44:55 UTC
Description of problem:
When the fw_ohci module is loaded (of course, the respective hardware should be
present; in my case it's a Gigabyte DS3 motherboard (Intel P965 chipset) with a
onboard OHCI Firewire controller) the computer locks up when resuming from a
suspended state. Suspend was working fine with Fedora Core 6 up to latest fc6
kernel updates (2.6.20), and cheased working as soon as I upgraded to Fedora 7
(also 2.6.20).

Version-Release number of selected component (if applicable):
kernel-2.6.21-1.3228.fc7

How reproducible:
Always

Steps to Reproduce:
1. Boot in single mode (fw_ohci should be loaded automatically)
2. Enter suspend mode: pm-suspend
3. After computer turns off, turn the power back on
  
Actual results:
Computer locks up

Expected results:
Computer wakes up

Additional info:
The try the same sequence but rmmod fw_ohci first, the computer will wake up
just fine.

I can confirm this on i686 too.  Exactly same behavior, on resume the caps-lock 
light starts blinking indicating a kernel panic.  Unloading the fw_ohci module 
before suspend fixes the problem.

Hello,

I'm reviewing this bug as part of the kernel bug triage project, an attempt to
isolate current bugs in the fedora kernel.

http://fedoraproject.org/wiki/KernelBugTriage

I am CC'ing myself to this bug and will try and assist you in resolving it if I can.

There hasn't been much activity on this bug for a while. Could you tell me if
you are still having problems with the latest kernel?

If the problem no longer exists then please close this bug or I'll do so in a
few days if there is no additional information lodged.

Cheers
Chris

This bug has been fixed at some point during summer kernel updates, at least for
me. I think version 2.6.22 doesn't have this bug anymore.

I will close the bug.
