The system seems to enter the S3 state correctly, but when I turn back on it freezes completely. I tried booting with no modules and no processes loaded (init=/bin/sh) and with a serial console, but I can't see anything helpful. What I see is this: > kjournald starting. Commit interval 5 seconds > sh-3.00# mount -t proc proc /proc > sh-3.00# mount -t sysfs sys /sys > sh-3.00# echo C057 > /proc/acpi/wakeup > sh-3.00# cat /proc/acpi/wakeup > Device Sleep state Status > C057 5 enabled > sh-3.00# echo mem > /sys/power/state > radeonfb (0000:01:00.0): suspending to state: 2... > PM: Entering state. > hwsleep-0307 [04] acpi_enter_sleep_state: Entering sleep state [S3] After that, it seems that the system goes to sleep. There is nothing on the screen, the HD stops, and the power light starts blinking. However, when I turn the machine back on it freezes completely. The HD starts, the power light comes on, but the serial console is unresponsive, the keyboard doesn't seem to work, and it won't turn off again, even if I hold the power button for 5 seconds. I am using a vanilla 2.6.11-rc3 kernel with the swsusp2 patch. Is there anything I can do to help debug this? I have acpi debugging compiled into the kernel, but I don't know how to use it. Any info would be appreciated!
