Description of problem:
After updating from to 184.108.40.206-20 my laptop does no longer suspend.
Well it does suspend just fine but hangs on resume with white lines on the
screen so that I have to power it down.
Suspend to disk also does not work. It just shut down X and does nothing instead
of suspending. But it powers down cleanly when pressing the poweroff button.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
2. try to resume
1. try to hibernate
hangs on resume when suspending to ram
hangs on suspending when suspending to disk
should suspend and resume just fine like all 2.6.21 based kernels did.

Laptop is a Zepto 6615WD.
I also tryed pci=nommconf and pci=nomsi and the results where the same.
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.
nope if something has changed I would have posted it here .. I tested suspend
with all new f7 kernels after this one all had the same issue. even the 2.6.23
based rawhide kernels fail in the same way.
thx for the help offer btw.
If you can try some of the following it would be helpful (taken from triage page):
# Find out if the system is locked up completely by hitting the caps lock key.
* If the capslock light doesn't toggle, the system is completely dead. Try
again, but this time before suspending, activate the pm_trace functionality with
echo 1 > /sys/power/pm_trace. This reprograms the real time clock to contain a
few bytes of information which we can use to diagnose which driver failed to
resume. After the hang, reboot, boot up again, and save the output of dmesg.
* If the capslock light does toggle, then the system did come back up, and
it's possible that we just failed to reinitialise the video.
http://people.freedesktop.org/~hughsient/quirk may contain further useful
information to diagnose this problem. It may also be useful to initiate the
suspend from a tty (ctrl-alt-f1) and run pm-suspend ; dmesg > dmesg.out ; sync
by hand. Upon resuming you'll now have some more debug info to sift through.
Additionally, this way when it resumes, you already have a console logged in
from which you can type commands 'blind'. Trying vbetool post for example may
bring things back to life.
# Try rmmod'ing various modules before doing the suspend. If this makes things
work again, retry with a smaller set of modules unloaded. Keep retrying until
you narrow down which module is to blame.
# Another trick that sometimes works to force video to come back up is to enable
the BIOS password. This makes the system resume in a VGA text mode that the
kernel recovers from a lot easier. Not a real solution, but it can help to
diagnose other problems.
You may also be interested in the comments found in the following thread
regarding suspend/resume with the nv driver (I take it you are using this rather
than the nvidia driver?):
I did some debugging with kernel-220.127.116.11-10.fc7 (which has pm_trace support for
x86_64). The culprit was firewire. After unloading the modules suspend worked
The device causing the failure was:
05:06.1 FireWire (IEEE 1394): Texas Instruments PCIxx12 OHCI Compliant IEEE 1394
I compared the firewire code with that from 2.6.21 (which worked) and ironically
the 2.6.21 had no suspend code at all so the added pci_suspend / pci_resume
functions seem to be the cause of it hanging (look up the box) during resume.
Due to lack of firewire device I cannot confirm if it worked before after resume
at all, but atleast it did not hang the system.
I'm guessing the problem still exists so am adding Stefan to this as he might
have something to add that may help.
I interpret comment #5 as: The culprit is the firewire-ohci module. Right?
I have sporadically tested it only with suspend(toRAM)/resume on a C2D + 945GM
based x86-64 PC and with APM suspend(toRAM)/resume on an old Pentium MMX
notebook. Works for me[TM]. I only tested mainline kernels, and I haven't
tested hibernate/restore yet.
The history of suspend/resume|hibernate/restore support in the new firewire
drivers in mainline Linux kernel:
- implemented .suspend and .resume methods in 2.6.22(-rc*)
- fixed an issue with iBook G3 and older Powerbooks in 2.6.23(-rc*) and 18.104.22.168
- fixed loss of SBP-2 and other protocol functionality after resume in

Which seems to have broke suspend for me.
I don't know if it worked after suspend before but atleast the system did not
hang on resume.
> - fixed an issue with iBook G3 and older Powerbooks in 2.6.23(-rc*) and 22.214.171.124
seems to be unrelated to my hardware; tests with f8 (2.6.23.x) seems to confirm

have not tested any 2.6.24 kernel with suspend.
might give it a shoot if you think that it will change something.
If you need any more information fell free to ask.

Without the methods, the firewire stack ceased to function after a

I don't track Fedora kernel sources; some of the firewire updates which went
into mainline after 2.6.23 was released may have already appeared in Fedora
kernels which feature a 2.6.23.* package name. In the particular case of this
update, I believe it won't do good nor bad on your system. It only fixes how
the Linux PC represents itself to external nodes on the FireWire bus.
Things that need to be done by someone are
- check whether the bug exists in the latest mainline kernel too
- if yes,
- debug and fix it there,
- backport fix into Fedora kernels if appropriate.
- if not,
- determine what to backport from mainline to Fedora in order to fix
Fedora as well.
I will eventually try to set up a test PC for hibernation, but I don't know when
I can do this and whether that PC will crash too. What I or anybody else who
attempts to debug this needs are diagnostic output (kernel panic message) and
probably direct access to the crashing machine for hands-on testing of candidate
(PS: "-if yes, - debug and fix it there": If mainline doesn't have a fix for
it yet, then debugging can of course as well proceed on a Fedora kernel rather
I'm going to hijack this bug... :)
This seems to be fixed in 126.96.36.199-7.fc8.
Removed my hack that unloads firewire-ohci from /etc/pm and I can still suspend
and resume without problems.
Cool. Now I wonder how this was fixed. :-)
While it'd be nice to know exactly how this got fixed, due to lack of bandwidth,
I'm going to just close this one CURRENTRELEASE. :\
