Red Hat Bugzilla – Bug 246256
fw_ohci.ko prevents kernel from correctly leaving suspend
Last modified: 2007-11-30 17:12:08 EST
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
Version-Release number of selected component (if applicable):
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
Computer locks up
Computer wakes up
The try the same sequence but rmmod fw_ohci first, the computer will wake up
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.
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.
