Comment 0 for bug 708286

On this system (Toshiba Tecra R700 with i7 processor), suspend apparently works fine: the system enter sleep, the power light flashes to indicate sleep.

When pushing the power button to turn back on, the system appears to come back but is unresponsive: display is turned off, CPU fan spins to maximum speed, and the system can't be pinged or accessed through the network.

Hibernate behavior is as follows: the system enters hibernation fine. Upon trying to wake it up, it has the same behavior as when suspending (see above). However, if I re-power-cycle the system, it boots up and de-hibernates as expected, picking up where it left off.

We're using Maverick with latest updates.

- Steps to reproduce
1- Install Maverick, apply latest updates
2- Put the system to sleep
3- Try to wake up by pressing power button

- What I expected to see: the system coming back up where it left off.

- What I saw instead: System unresponsive as described above.

- Did the machine break while going to sleep or waking up?
Observing suspend and hibernate behavior leads us to believe it's an issue while going to sleep.

- Is the problem reproducible?
  Yes, this happens every time.

- Did it work before?
  No

- Do you end up with flashing caps lock or similar?
  No

I followed the steps in DebuggingKernelSuspend and got no useful information (no "hash matches" messages).

We also tried this mainline kernel:
http://kernel.ubuntu.com/~kernel-ppa/mainline/drm-intel-next/current/linux-image-2.6.38-997-generic_2.6.38-997.201101260912_i386.deb
Problem still persists.

This machine is primarily used for testing purposes, so it's available to run any tests that might help with this issue.
