Ergo this one. Your new RTC driver seems to work for me (thinkpad x60), but no, I can't get wakeup using RTC to work: root@amd:~# echo HDEF > /proc/acpi/wakeup root@amd:~# cat /proc/acpi/wakeup Device Sleep state Status LID 3 * enabled SLPB 3 * enabled DURT 3 enabled EXP0 4 enabled EXP1 4 enabled EXP2 4 enabled EXP3 4 enabled PCI1 4 enabled USB0 3 enabled USB1 3 enabled USB2 3 enabled USB7 3 enabled HDEF 4 enabled root@amd:~# sync root@amd:~# sync; /tmp/rtcwake -s $((2 * 60)) -m disk rtcwake: wakeup from "disk" using rtc0 at Sun Aug 27 16:54:49 2006 root@amd:~# Any ideas? (I tried suspending to RAM, too; no change). Is acpi-rtc code likely to be merged?
