A few ACPI questions
Hello,
I've a few questions about some ACPI issues, but first some specs would probably be helpful. The computer that I'm using is a Mitac 8355 laptop with an Athlon64 3200+ running a 2.6.10 kernel. For lspci see http://users.wpi.edu/~chanin/acpi/lspci.
The first question is about the dsdt (which you can view - well, you can view my slightly edited version, just fixed the obvious things - at http://users.wpi.edu/~chanin/acpi/dsdt.dsl), there's a 'function' (if it can be called that) at line 1756. It's supposed to always return something but does not always do so. I looked around and I've seen some people making it return 0 at the end, 1 at the end, TMD0 at the end, and 1 at the beginning. So I really had no idea precisely what fix would be appropriate. Or - does it not even matter? It is just a warning after all, and IDE transfers seem to be working fine (in conjunction with ACPI perhaps less so, but that's neither here nor there.)
The other thing of note with the dsdt is around line 772 where it sets OSFG based on what it was set to before and the length of the operating system's name. I've tried changing the OS name to match the lengths given with no changes in anything pretty much. Looking through the file I do not even see where OSFG is ever accessed. Just figured it might matter too, as it is a small anomaly.
The more noticeable problem that I'm having is with sleep states. Standby seems closer to working than S3, but I'm not so sure. Upon switching to standby the screen will flash back and then turn right back on. The following is logged:
Feb 24 22:14:37 laptop Stopping tasks: ======================================================| Feb 24 22:14:37 laptop Restarting tasks... done
S3/Mem causes a kernel panic, and I'm currently trying kernel's with less stuff and/or newer kernels to see if I can get it to do something more useful.
So any recommendations on what I should do with the dsdt? Or any next steps for fixing sleep states, I've already tried everything in tricks.txt and the other documentation, although informative, wasn't incredibly practical for my siltation.
Thanks,
Isaac
P.S. For any replies could you cc the message to me too please - I made an attempt at joining the list, but couldn't get a confirmation of my confirmation e-mail, so I'm not 100% sure that I'm joined yet. Thanks again.

Try suspend-to-disk, first. See Doc*/power/swsusp.txt.
