Description Austin Jackson 2006-06-25 10:09:38 EDT
Description of problem:
kernel-2.6.17-1.2139_FC5 breaks i810 resume from sleep

Version-Release number of selected component (if applicable):

How reproducible:
every time

Steps to Reproduce:
1. boot 2.6.17-1.2139 on a system using the i810 driver (mine is a i915 GM)
2. suspend the computer to ram
3. wake the computer
Actual results:
the screen remains blank, but the system is up (responds to keystrokes to restart)

Expected results:
display wakes up as it does in kernel-2.6.16-1.2133_FC5

Additional info:
I noticed this with a Dell Latitude X1 with an Intel i915GM chipset.
Comment 1 Philippe Troin 2006-06-25 21:51:52 EDT
I can also confirm that 2.6.17-1.2139_FC5 breaks suspend-to-RAM on a Fujitsu
P7120 with a i915 graphics card.

2.6.16-1.2137_FC5 used to work fine (with some slight tweaks, like adding
'acpi_sleep=s3_sleep,s3_mode' to the kernel command line.

Comment 2 Austin Jackson 2006-06-26 08:09:45 EDT
Just to be clear, my machine is suspending and waking with settings used with
the previous kernel 2.6.16...  The display is just not waking.
Comment 3 Manuel Morales 2006-06-26 13:22:47 EDT
I am having the identical problem on a Dell Latitude D600 with ATI Radeon R250
(FireGL 9000) video card and xorg driver.
Comment 4 Austin Jackson 2006-06-26 17:08:22 EDT
Workaround (works on a Dell Latitude X1):


Option "VBERestore" "true"

to your xorg.conf device section for your video device

And before suspend issue a chvt 8.  On resume, issue a chvt 8; chvt 7

I have added these commands to my sleep script.
Comment 5 Manuel Morales 2006-06-27 07:45:08 EDT
Things are working fine for me now. Not sure if it was the recent update or the
switch to gnome-power-manager.
Comment 6 barry gould 2006-06-27 14:12:03 EDT
> before suspend issue a chvt 8.  On resume, issue a chvt 8; chvt 7

Fixes the same problem for me on Dell Latitude D800, using 'nv' driver.

Comment 7 Radek Bíba 2006-06-28 16:29:49 EDT
Not sure if it's exactly relevant to this bug report or not but resuming from
suspend-to-disk with kernel-2.6.17-1.2139_FC5 kills the X-server (using i810)
for me, making the whole suspend/resume feature useless. Kernel boots, says
it's going to resume from the swap partition, starts reading, displays turns
white and after a while, busy cursor is displayed and then gdm is started - on
tty8. tty7 becomes unusable and this is added to /var/log/Xorg.0.log.old (and
Xorg.0.log is newely created):

2.6.17-1.2145_FC5 has the same problems.
Comment 9 Philippe Troin 2006-08-23 18:16:09 EDT
Fixed in 2.6.17-1.2174_FC5.

> Fixed in 2.6.17-1.2174_FC5.
Well, in my case, pm-hibernate is OK. pm-suspend causes a weird behavior: all
windows are "content-free", panel is empty, desktop icons are black... not really
usable desktop. If I enable VBERestore then IRQ 10 becomes disabled - no USB port
1, no sound; text on virtual terminals flickers wild. Not really usable desktop
Comment 11 Dave Jones 2006-10-16 13:42:11 EDT
A new kernel update has been released (Version: 2.6.18-1.2200.fc5)
based upon a new upstream kernel release.

Please retest against this new kernel, as a large number of patches
go into each upstream release, possibly including changes that
may address this problem.

This bug has been placed in NEEDINFO state.
Due to the large volume of inactive bugs in bugzilla, if this bug is
still in this state in two weeks time, it will be closed.

Should this bug still be relevant after this period, the reporter
can reopen the bug at any time. Any other users on the Cc: list
of this bug can request that the bug be reopened by adding a
comment to the bug.

In the last few updates, some users upgrading from FC4->FC5
have reported that installing a kernel update has left their
systems unbootable. If you have been affected by this problem
please check you only have one version of device-mapper & lvm2
installed.  See bug 207474 for further details.

If this bug is a problem preventing you from installing the
release this version is filed against, please see bug 169613.

If this bug has been fixed, but you are now experiencing a different
problem, please file a separate bug for the new problem.

Thank you.

Cool, looks like suspend-to-ram works again here. But, for some reason still no

sound was being produced after waking up, although the player application
show any error and no channel appeared to be muted. Attaching a part of log,
shows an problem at kernel/rwsem.c, among other messages.

Leaving in NEEDINFO as I'm actually not the reporter of this bug.
Comment 13 Radek Bíba 2006-10-20 16:43:40 EDT
...Forgot to mention, sound started working again after running s-c-soundcard and
playing the test sound. Not sure what exactly helped, though.
Comment 14 Dave Jones 2006-10-20 17:38:28 EDT
the rwsem issue has been reported in a separate bug. I'll look into that soon.

For sound problems, the quickest way to get them fixed is to report them in the
upstream alsa bugtracker at https://bugtrack.alsa-project.org

I'm fairly confident this is going to be fixed for Austin too, so I'll close
this out. (Feel free to reopen if I'm wrong)
