Created attachment 91530 [details] General system information Hello, I have a Radeon HD5770 and I cannot use s2ram with Linux kernel 3.13.rc*. It has been working fine for years, currently with kernel 3.12.0. I tried to bisect on the Linus tree and the first commit where it started failing is # first bad commit: [be51e4a78155ff6c5d9299bf726e86b554e21117] Merge tag 'drm-intel-next-2013-10-18' of git://people.freedesktop.org/~danvet/drm-intel into drm-next However, the symptoms look slightly different. With that commit, the system hangs on suspend. With later revisions, it reboots after 3-5 seconds. Not sure what makes the difference, maybe it's the new option CONFIG_DPM_WATCHDOG but OTOH I disabled it later and it still keeps rebooting. And I am not sure which kernel module is exactly the troublemaker, I excluded "radeon" from the initramfs list and this seemed to make the difference (suspend worked from initramfs environment) but maybe something else is involved too. I am attaching some information (messages, pci list, config) which might be useful. If you want me to work with kgdb/kdb, this may take a couple of days until I can get a COM port breakout cable for the mainboard.
