When resume from suspend to ram, it appears the busy mouse cursor and the system freezes. Keyboard does not work. Although it is possible to enter by SSH, but /etc/init.d/gdm restart does nothing. Unable to Recover X.

It is stochastic, a longer suspension more likely (1 hour, 95%). If you play videos or DRI applications, even more likely freezing after suspend.

Hard and Soft:
Ubuntu 7.10 Gutsy, xserver-xorg-video-intel 2:2.1.1. Thinkpad X41 Tablet.

I also tested it with the git version, latest update <eric@anholt.net>  2008-02-08 20:34:04, this always freezes, but instead of a mouse cursor appear colors. (Besides With this driver is not working DRI, possibly for not change kernel modules drm, i915 ??).

Other experiences I think are related to this driver: 

1.Gdm frecuently auto reboot with X error logs, Gnome-Compiz start with problems, panel and screen appearance, disappearance,.. (This seems to change with some versions driver intel I have been testing:  xserver-xorg-video-intel_2.1.1-0ubuntu10~bwh4_i386.deb, xserver-xorg-video-intel_2.1.1-0ubuntu10~pcjc2.2_i386.deb ).  

2. DRI apps (Celestia, Google Earth,..) crash with xrandr rotated and freezes the whole system.
3. The new Ubuntu Hardy Alpha 4 livecd, freezes on a black screen instead of starting X.

Comment 1 Liken Otsoa 2008-02-18 02:01:26 UTC

A new clue about this bug.

When X freezes after suspend (a restarting X lockup cycle and keyboard blocked), you can enter in the machine with SSH. WELL: A REBOOT WITH KEXEC DOESN'T SOLVE THE PROBLEM. Linux reboots and X with intel driver freezes again. It's necesary a hard system reboot. 

#kexec -l --append="`cat /proc/cmdline`" --initrd=/boot/initrd.img-`uname -r` /boot/vmlinuz-`uname -r`
#kexec -e

Other tests with SSH when X is freezed:

#/etc/init.d/gdm stop
# (Kill -9 gdms if necesary)
#nano /etc/X11/xorg.conf (Change intel to vesa driver)
#/etc/init.d/gdm start (OK. X goes with VESA)
#/etc/init.d/gdm stop 
#nano /etc/X11/xorg.conf (Change again to intel or i810 driver)
#/etc/init.d/gdm start (Freezes Again, lockup cycle)

Liken, Are you able to access the system after X freeze? Would you please verify the BusMaster Bit of PCI as bug# 14031? It's also a Thinkpad X41. thanks.
Comment 3 Jesse Barnes 2008-02-19 18:00:31 UTC
Liken, can you use the intel_reg_dumper tool from src/reg_dumper to get a snapshot of the regs after a fresh boot (before starting X) then after resume (again w/o X running) so we can see if there are differences?  So:
  - boot up
  - capture reg dump before starting X
  - start X
  - chvt 1
  - suspend
  - resume
  - capture reg dump
Then attach the dumps to this bug.

intel_reg_dumper compiled from same version. (Git Version is incompatible with
libpciaccess-dev 0.8.0)
Ubuntu 7.10 Gutsy (With vesafb active to text boot but to remove it does not
solve the problem. LiveCD freezes equally at suspend/resume. And in Hardy
LiveCD with intel 2.2 Black Screen instead of starting X)
Comment 11 Liken Otsoa 2008-02-24 12:21:14 UTC
This Bug #192873 is ALIVE in Hardy Alpha5 LiveCD.

Comment 12 Liken Otsoa 2008-03-02 11:12:12 UTC
I rectify previous message.

In Hardy Alpha 5 (Last Updates, installed in HD) X doesn't freezes after resume from suspend to ram. This only happens with livecd, perhaps a problem with USB CD-ROM or something.

In Hardy the bug with intel-video-driver is worse, it crashs sporadically, you suspend or not.

I report this bug, log files and intel_reg_dumper in:


IBM Thinkpad X41 Tablet
Ubuntu Hardy Last Updates
xserver-xorg-video-intel 2:2.2.1-1ubuntu2
mesa 7.0.3~rc2-1ubuntu1
kernel 2.6.24-11-generic

-------Significative errors in X:

---When it crashes: 

Error in I830WaitLpRing(), timeout for 2 seconds
Fatal server error:

--.When it wants to restart:

(WW) intel(0): PRB0_CTL (0x0001f001) indicates ring buffer enabled
(WW) intel(0): PRB0_HEAD (0xc0a1a91c) and PRB0_TAIL (0x0001aa70) indicate ring buffer not flushed
(WW) intel(0): Existing errors found in hardware state.

I see is now exactly the bug# 14031
