I flashed the BIOS with IBM's latest image and the oops went away. However, suspend (hibernate) still doesn't work! Now, both suspend and standby give a standby. I cannot get a suspend, either by pressing the suspend key combination or using the apm -s command. Neither one will do a hibernate, only a standby. Any ideas on this one now?
