[arch-general] Problems suspending since 2.6.33
Hello guys, since I upgraded for 2.6.33 several weeks ago, I encounter problems when suspending (or more precisely waking up) my machine. Since everything worked fine for month/years I first thought about a bug which might get fixed soon but while 2.6.33 is pretty settled and I couldn't find something in bug track I think the problem is somehow specific to my machine. As mentioned everything worked fine. I simply used 's2ram -f -p -m' to suspend my machine (need the parameter due to my ATI graphics card). No it seems suspending works fine but waking up crashes. When waking the computer up the screens stay black. In addition the HDD LED turns on for ~8sec and subsequent turns off. That's it. It seems dead. Also "blind" commands have no effect... I tried several parameter combination as well as pm-utils (which error-free logs confirm my assumption that at least suspending works fine). Also Xorg seems not to be the problem, since even suspending from a blank tty (without xserver running at all) does not make the computer wake up afterward. Any ideas on this? My machine: Intel P35 Chipset Intel Core 2 Duo E8400 ATI Radeon HD 3600 regards and thank you Michael
I think ATI KMS (kernel mode-setting) was merged or enabled in 2.6.33? That would explain why this kernel; why the same issue happens suspending from the console; why that graphics-quirk doesn't work the same (I don't have s2ram installed since I use pm-suspend (via GNOME), but I guess that's what you meant in regards to -f, -p or -m). Suspend ought to work though (did you try testing 'echo mem > /sys/power/state' too? I think that's mostly the same as pm-suspend nowadays, maybe), but it's understandable since there are new code-paths, if indeed it's graphics that are at issue. If you want to debug I'd suggest try grabbing 2.6.34 kernel26 and -firmware from testing (e.g. you can download the packages from online), as there's a chance it's been fixed there (my Intel KMS-related issues were, for example) Also Did you search? A quick search for
2.6.33 suspend ATI Radeon HD 3600 led me to e.g. a bug here that links to an archlinux thread that contains a couple suggested workarounds to try (e.g. does disabling networking before suspending fix your resume?) http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=573118#10 -- those may be completely unrelated issues or then again they may not.
