I've switched to 2.6.0-test11, and was pleasantly surprised that
suspend-to-ram / suspend-to-disk (Patrick's version) works very well.
It even somewhat fixes (by initialising properly on resume) troubles with
miniPCI 3c556 NIC.
(bug #1188 in bugzilla). One problem (not a showstopper, but somewhat
annoying) is audio device driver failing to resume correctly from STR. No
oops, but no sound after resume either, until sound driver is
relevant messages in dmesg:
Nov 28 02:02:48 localhost kernel: ALSA sound/pci/cs46xx/cs46xx_lib.c:1420:
open front channel
Nov 28 02:02:58 localhost kernel: ALSA sound/core/pcm_native.c:1267: playback
drain error (DMA or IRQ trouble?)
for ALSA driver and
Nov 28 10:50:00 localhost kernel: cs46xx: drain_dac, dma timeout? 1034
With APM this feature worked corectly.
I've looked briefly into the driver code (cs46xx_lib.c), but quickly realised
I'm not knowledgeable enough to try to fix the problem. I've tried to
reproduce initialisation sequence (by copypasting relevant code from
snd_cs46xx_create to snd_cs46xx_resume), but without success.
With all the best, yarick at relex dot ru.
