I can't resume from suspend-to-ram on my Sony Vaio VGN-FS215S. I tryed debugging the thing a little with pm_trace and my dmesg says: [...] ACPI: (supports S0 S3 S4 S5) Magic number: 4:804:766 hash matches device serio4 [...] /sys/bus/serio/devices/serio4/description says: i8042 AUX3 port and /sys/bus/serio/devices/serio4/driver/description says: PS/2 mouse driver But now I'm stuck, and don't know what to do!
