Hi! I'm running Linus' git tree on my thinkpad T60. It generally seems to work fine after suspend to disk. However, the system does not come out of suspend to ram, with screen staying blank. I'm looking for hints for debugging this. If I set suspend/resume event tracing, I see this in dmesg after reboot: dmesg -s 1000000 | grep 'hash matches' hash matches drivers/base/power/resume.c:42 hash matches device serio2 serio2 seems to be the psmouse device: ls /sys/bus/serio/drivers/psmouse/ bind bind_mode description serio0 serio2 unbind Does this mean the mouse driver blocks the resume? I've rebuilt psmouse as a module, unloaded it before suspend, and now I see the same behaviour but after reboot: dmesg -s 1000000 | grep 'hash matches' hash matches drivers/base/power/resume.c:42 hash matches device i2c-9191 Which is somewhat weird because ls /sys/bus/i2c/devices does not list any i2c devices I could continue disabling stuff - but I am looking in the correct place even? How do you debug resume issues? Thanks, -- MST
