--- Comment #3 from Thomas Richter <t...@math.tu-berlin.de> ---
Yes, suspend to disk is called hibernation. Sorry for the confusion - suspend
to ram is broken. I checked various other releases, it seems to be consistently
broken over all of them. The problem is not related to any kernel drivers - I
unloaded as many as possible but still get a hang. Suspend to RAM is also
broken on Windows98SE, but works on Windows XP. The R31 does not have an APM
bios, hence this option is unfortunately not available.

I also tried the "resume" kernel debugging tricks that store the last known
location of the kernel in the RTC, but unfortunately did not get anything. It
seems to be stuck somewhere before it actually reaches the parts that store
information into the RTC.

In the meantime, I made the DSDT compile with iasl, fixed the wrongly declared
memory regions and added the missing  returns for \_WAK, but without success.
iasl compiles the fixed ACPI table correctly, the kernel loads them, but no
avail. Probably the RAM looses its contents? Is there known information for the
i830 chipset what one has to do to keep the RAM powered up?
