Good morning kernel hackers,

as reported before, the system does not freeze completly anymore
and even reports errors after the nth time resumed (about 10 cycles
needed). Currently the display gets redrawn VERY slow, if at all.
Restarting xorg does not help, rebooting the system does.

The problem though continues to exist on latest kernels,
tested here are 2.6.36-rc6-00137-g7c6d45e and 2.6.36-rc7-00124-g85a3318.

This happens on the X200 and X201 (both tested).

Attached are both dmesg and xorg log from last two cases.

If there are any known workarounds, please let me know (besides not suspending).

Cheers,

Nico

It seems that this happens more often/always when a second
monitor is enabled using xrandr.

At least the two last times the slow drawing state occured
directly after the first resume with an enabled external
monitor.

Cheers,

Nico
