Subject: Kohjinsha sleep problems

Hi!

On kohjinsha, wakeup code does not seem to be reached at all. I tried
looking around FACS, but it seems very empty:

(none):/data/l/kohji# acpidump -t FACS
FACS @ 0x1f7bffc0
  0000: 46 41 43 53 40 00 00 00 00 00 00 00 00 00 00 00

iasl[1864]: segfault at 080e5000 eip 08062f5c esp bf9d1e50 error 4

In dmesg I find:

DMI 2.3 present.

ACPI: PM-Timer IO Port: 0x9c10

What should be done to debug this? I guess FACS is strictly neccessary
for sleep support?
