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):

How reproducible:

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.

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


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.


Comment 3 Andrew Zabolotny 2007-09-18 09:45:52 UTC
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.
