[Bug 454402] Re: [TOSHIBA TECRA M9] suspend/resume failure [non-free: nvidia]

[vgyo]

 Yes It is still an issue , with slight changes

  Bug description:

General BUG Description: Suspend works, resumes but screen always remains black with no cursor  
             Hibernation always throws acpi errors; sometimes, after repeated tries to turn off HDD, it succeeds
             Other times, hibernate can't turn off HDD and cut power completely to screen, so I keep pressing the power 
             button until shutdown. After, if I press the power button, it resumes normally.

Laptop : Toshiba Tecra M9
OS : Karmic Koala x86
Graphics card : Nvidia Quadro NVS 130M

2.Machine is never able to restore the screen on wake-up (screen is blank, and no cursor)
3.Machine hibernates abnormally:

      3.2.Sometimes(3-4 out of 10) hibernate cannot turn off HDD and power completely off the screen
4.Machine always resumes normally from hibernation

Suspending from text mode

sudo pm-suspend --suspended the machine

DebuggingKernelSuspend

"resume-trace" debugging procedure for finding buggy drivers

sudo sh -c "sync; echo 1 > /sys/power/pm_trace; pm-suspend"
 
After the above, black screen tried to fix filesystem errors on my linux partition I checked yes and rebooted

dmesg > dmesg.txt --see attached dmesg.txt file

Hibernating from text mode

sudo pm-hibernate--Did not turn off HDD, cursor kept blinking on a black
screen

Per sub-system hibernate testing

running the commands :

sudo -i

# lsmod > lsmod.output.txt

# echo devices > /sys/power/pm_test
# echo platform > /sys/power/disk
# echo disk > /sys/power/state
# dmesg > /tmp/dmesg-devices-platform.txt

# echo core > /sys/power/pm_test
# echo platform > /sys/power/disk
# echo disk > /sys/power/state
# dmesg > /tmp/dmesg-core-platform.txt

# echo core > /sys/power/pm_test
# echo reboot > /sys/power/disk
# echo disk > /sys/power/state
# dmesg > /tmp/dmesg-core-reboot.txt

did not produce any lsmod file
