radeonhd driver doesn't resume from suspend on r6xx/r7xx

[nicofari]

Binary package hint: xserver-xorg-video-radeonhd

I've just purged fglrx (ati proprietary) video driver to install radeonhd, simply configured it into xorg.conf and verified it loads in /var/log/Xorg.0.log, I suspended to ram my Acer Aspire 5920G with Radeon HD3470 card.

Resuming gives me a seeming-alive (power led is ON), really-dead (blank unlit screen, no response to VT switching, nor to Alt-SysRq-REISESUB attention keys).

No further interaction is possible, forced poweroff is the only thing to do.

I get the same results with 1.2.5-1 from Debian unstable. (Lenovo Thinkpad T60p, Mobility FireGL V5250.)

I've an issue with the same hardware as Russ, too. My T60p seems to wake up fine at first. I can even move the mouse cursor and see the password prompt of the KDE screensaver, but I'm unable to type in my password. After a couple of seconds the mouse cursor gets harder and harder to move as if an application is eating up all CPU power. Eventually X freezes after about 5 seconds.

Suspend to RAM and suspend to disk worked perfectly fine with 8.10 and fglrx video driver.

Follow up:

I did some additional testing. Suspend to disk and suspend to ram are working fine with the *radeon* driver. Only the *radeonhd* video driver is playing havoc with suspend. I also run pm-suspend from the text console while X11 was running with a radeonhd driver. My system came up just fine and worked until I switched to VT7. As soon as I switched back to X11 the compuer froze.

There were some suspend/resume fixes for r6xx/r7xx in the radeonhd 1.2.5 release. Can you please try the test package in my PPA https://launchpad.net/~tormodvolden/+archive/ppa ?

[Christian Heimes (heimes)]

Sure, I'll give it a try tomorrow and report back as soon as I have results.

[Christian Heimes (heimes)]

Good work, Tormod! After I've updated to xserver-xorg-video-radeonhd_1.2.5+git20090415.950842aa-0ubuntu0tormod_amd64.deb suspend to RAM with radeonhd works again. Good work!

This was probably fixed by http://cgit.freedesktop.org/xorg/driver/xf86-video-radeonhd/commit/?id=9d2a508892f16572127d192497bcf505556538b8
We can probably add this to the current package, but I would rather see an SRU with the released 1.2.5 version.
