Suspend Crashes, Does suspend work for you on OpenBSD? Options

[fquindos]

Hello. I have consistent crashes when suspending for more than a few minutes. It doesn't matter if I click the power button, use "apm -S", "zzz" or close the lid with lidsuspend=1. Pressing the power button after it has been suspended for a short while works, but I get console messages saying, for example

wd0e: aborted command writing fsbn 5248 of 5248-5251 (wd0 bn 1562608; cn ...
wd0: soft error (corrected)

However, if I let the Zaurus sleep for 15 - 30 minutes, after pressing the power button the disk drive (green led) comes up, but the display remains black and the keyboard doesn't work. I need to do a reset.

Does anyone have any suggestion? Does it work for you?

By the way, I have a 3200 and an OpenBSD 3.9 snapshot. It also happened with 3.9-release and a prerelease snapshot.

Thank you,
Francisco

Okay, just to be more precise to the symptoms:

When suspending in console (both zzz and closing the lid), resume will produce a very short white flash on the screen, followed by screen black out. Typing "wsconsctl display.backlight=100" doesn't work at all.
After waiting a while i see the green light on, which i guess is the system trying desparately to resume the microdrive, but keeps failing (sometimes i see the error message of failing to reset wdc0 blah, but most of the time just everything in the dark).

When suspending in X, resume usually can bring the screen back, but then the system freezes. After a while the screen goes dark and the green LED turns on, which probably also indicate the harddrive reset failure ...

So here i would really appreciate clear answers to the questions ( the more i read the documentation and the tips pages, the more i seem to get confused, just because things do not work as described )
Sorry for getting a bit paranoid now because i am beginning to get a bit frustrated after spending two weeks without getting a stable enough system working.

1) Which version is actually more preferred? The snapshots (which I've been trying to get working but always got errors) or the "official" releases (from the 4.1 dir)?

2) What should I put in /etc/fstab about wd0 if I install the snaphot in one big partition?

3) Should writecacheenable be enabled or not?

4) About swapfile: is it fine to set up swapfile after installing *everything* (including all the distribution sets) in one big partition?

5) And of course, what is the source of the suspend trouble? Frankly, I have already tested a few dozen times (believe me) trying to exhaust all the possibilities: with/without memory cards mounted, with/without cards inserted, with/without AC, with/without disk cache, with/without turning on mechdep.lidsuspend in /etc/sysctl.conf ...

well well,
i only use the button to suspend and resume (as i'm compiling a lot under the console), and it seems i've less troubles than you... by the way which zaurus model do you have ?

Mine is 3200.
Do you mean using the On/Off button to suspend only? I cannot resume when suspending this way.
Which version (snapshots or official release or your own build) do you use?
How do you partition the space?
What are your settings with respect to the harddrive(/etc/fstab, /etc/sysctl.conf, /etc/rc.local. etc)?
Sorry for asking so many questions. I tried mathemajikan's advice but the same story.
How can i use a machine which cannot suspend and resume properly?
