Latest working kernel version: 2.6.28-rc4-00011-g3ad4f59 Earliest failing kernel version: 2.6.28-rc4-00012-g1cfe62c Distribution: ArchLinux (testing repository enabled) Hardware Environment: Acer Extensa 4220 (Intel Celeron 550; Intel 965GM) 1. SMP disabled Prior to 2.6.28-rc4-00012-g1cfe62c 's2ram -f' was working just fine. Since 1cfe62c8010ac56e1bd3827e30386a87cc2f3594 when trying to resume the laptop lightens up for a moment, turns off for ~10 seconds, turns on for ~10 seconds with the screen completely blank and HDD LID blinking, quickly turns off and on, showing BIOS POST screen. Reverting this 1cfe62c... allowed me to restore s2ram functionality on both 2.6.28.3 and the latest git (it was 45c82b5...). Probably important note is that when I just had applied the patch (git diff -R 1cfe62c~1 1cfe62c >acpi-s2ram.patch) to my already built 2.6.28.3 and rebuild the kernel, it didn't work. I had to 'make clean' the source tree in order for the patch to take effect. 2. SMP enabled With SMP enabled s2ram ceased to work long ago. Somewhere between May 28 ( a939098~1 was the last compilable and working version) and Jul 11 (d9fc3fd fixed the last issue causing kernel panics). After reapplying d9fc3fd, 1a98fd1 and 55f2623 I managed to narrow down the interval to May 28-Jun 21 (f580366), but this is still very large. Anyway, this is another bug.
Hi, Orivej Will you please attach the output of acpidump? Thanks.

Bug 12642 seems to be the same as this: rmmod'ing psmouse allows my laptop to wakeup (tested on today's git only with SMP disabled).
There appears to be a conflict between the EC and the psmouse driver. Alex?

Alexey, I've tested your patch against kernel 2.6.29.1 with gentoo-sources patches (ArchLinux's kernel26-ice 2.6.29-3) only, and your patch doesn't help: laptop fails to wakeup as described in the first post. Rmmod'ing psmouse makes it wakeup just fine.
