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.</pre>
