--- Comment #37 from Keivan Moradi k.moradi@gmail.com 2010-12-13 05:27:18 --- I've followed gentoo documentation to enable standby on my workstation. When I run the command "hibernate-ram" in the console, system turns off but sytem freeze on resume from Suspend/Standby/Sleep. (monitor show a vertical rainbow) + (alt + sysrq + b cannot reboot the system).

hardware:dual xeon motherboard with only one 5540 cpu + very old ps2 mouse and keyboard + old x300SE (RV370) ati vga kernel: gentoo-sources (2.6.34 r12) + original kernel drivers.

When I've reconfigured the kernel to do not use ati drivers (I used vesa drivers instead), suspend work without problem. Now I'm sure there is a bug in the radeon drivers.

on my next experiment I've configured the kernel to use only ati driver under direct rendering manager (ie I've removed the ati framebuffer driver) -> this time system suspends and on resume there is color page with a blinking cursor but there is no working console. alt + sysrq + b can reboot my box.
