Description Konstantin Nikiforov 2012-01-31 20:58:52 UTC

Distrib: Archlinux current.
Issue is 100% reproduceable on 3.2.1, but NOT reproduceable on <3.2 (any older kernels).

Steps to reproduce:
0. Notebook Toshiba Sattelite A210 (see lspci[1])
1. Power up, boot to X
2. s2ram
3. wake it up using power button

Expected result: xorg can work
Result: xorg freezed, picture looks corrupted, but mouse pointer works.
In console (ctrl+alt+f1) infinite messages:
