Probably it crashes early in the wakeup code.  pm_trace only really starts to
work when you get to the drivers.

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.
