Probably it crashes early in the wakeup code. pm_trace only really starts to work when you get to the drivers. > And any common incantations that appease buggy ACPI implementations? It may be worth trying to put your system into acpisleep_dmi_table[] in drivers/acpi/sleep.c with init_set_sci_en_on_resume as the callback. Also please have a look at the acpi_sleep= options in Documentation/kernel-parameters.txt . Especially old_ordering is worth trying. Thanks, Rafael
