emerge --info

After echo starndby > /sys/power/state system freezes (black screen, ignore keyboard, even magic keys).

Useless actions:
1) pci=nocrs as a kernel parameter.
2) Disabling ASPM.

Actions, that force it work:
1) Disabling KMS and enabling fb drivers.
	or
2) Boot without loading graphic card firmware.

Kernels with correct suspending: 3.0.6 and older.
Kernels with incorrect suspendig: 3.1.6, 3.2.1-r2 and 3.2.2.

I have RadeonX550 (R300) graphic card.
I have not HPET timer.

Please post more information about the graphics driver / firmware you say causes the issue.

Comment 3 nehex 2012-03-12 12:59:25 UTC 
The graphic driver is "ATI Radeon" located in
Device Drivers
	-> Graphics support
		-> Direct Rendering Manager (XFree86 4.1.0 and higher DRI support)

Firmware is radeon/R300_cp.bin

And I attach kernel config for 3.2.1-r2

I don't know what else...
Comment 4 nehex 2012-03-12 18:06:07 UTC 
Another important thing: suspending works fine with disabled DRM_RADEON_KMS
which called "Enable modesetting on radeon by default - NEW DRIVER" in menuconfig.
But I have 720x400 in this case instead of 1152x864.
Comment 5 nehex 2012-06-24 14:19:28 UTC 
It works fine on 3.3.8 kernel (gentoo-sources). Thanks to all!
