Suspend freeze on a Thinkpad R31

Hi, Ive posted this to both the misc and the mobile lists, but without response, I was wondering if anyone could help shed some light on this problem. Thanks again,
Dave

Hi Im looking for advice or experiences from people who have used OpenBSD on a Thinkpad R31 (or model that implements the same APM in the BIOS I guess).

I am running OpenBSD current (required for the video support), but the APM support does not appear to work, where the problem is I am not sure, but I can give the following details of things I do know about the problem :

apmd appears to run successfully.

Calling :
apm -S : causes the laptop to go into standby and then immediately come out of it to the HDD power up password, where it freezes
(not responding to pings or connections, and no keyboard response)

apm -z : causes the laptop to go into suspend and then immediately come out of it to the HDD power up password, password is accepted and screen returns to previous state, however mouse and keyboard do not respond, and machine is frozen
(not responding to pings or connections, and no keyboard response)

During boot up machine gives the following dmesg lines : apm0 at bios0: Power Management spec V1.2 apm0: battery life expectancy 99%
apm0: AC on, battery charge high, charging pcibios0 at bios0: rev. 2.1 @ 0xf0200/0xb00

pcibios0: PCI IRQ Routing Table rev. 1.0 @ 0xfc800/144 (7 entries)
pcibios0: no compatible PCI ICU found: ICU vendor 0x8086 product 0x248c
pcibios0: PCI bus #2 is the last bus

And using either Fn-F4 or Fn-F12 cause the machine to crash to a terminal with no response, and a black screen, again no ping response or connections.

Do you need help?

These symptoms occur in exactly the same way, both from within X, and from a terminal.

I have upgraded the laptops firmware to the latest version, but also without change.

In addition I have also turned on the "machdep.apmhalt=1" line in sysctl.conf file, also without success, and have recompiled my kernel including the line "option APM_DISABLE_INTERRUPTS=0" once again without success.

I have tried turning off PCI related power options in the BIOS settings, and have also disabled all BIOS passwords. Still no luck.

After perusing the mailling lists and googling endlessly, I simply cannot find anyone else with an R31 which have anything to say about this.

If anyone can make any suggestions, or has similar experience, I would be greatly appreciative.

Cheers
