S3 resume and other ACPI questions

S3 resume and other ACPI questions

[Andre Eisenbach]

Hello ACPI devs!

I've recently bough a new AMD 64 notebook (Acer Ferrari 3400LMi). Here
are some ACPI related issues I have:

- S3 resume seems to turn on the machine, but the LCD stays dark and
the keyboard is not working.

- The battery information works, but get's "stuck" on certain values
(like 10% remaining) and doesn't update anymore. I lost power during a
DVD burning session because ACPI said I still had plenty left....

Are there any known problems/fixes?

How can I help debug/fix the problem?

Kernel is 2.6.10-gentoo-r7.

Thanks,
    Andre

Read Doc*/power/video.txt. Send me a patch when you get it working.

Hello Pavel, all,

I've read video.txt and it got me further actually. Thanks for that.

I've recompiled the kernel without any fbcon etc. and use the "radeon"
display driver within X windows (Gentoo patched version). This way I
can actually resume from S3 now, and get right back into X. Really
quickly, too.

However, the hard drive does not seem to fair so well. The hdd
activity LED remains on and the drive does not seem responsive (but
spinning). The laptop slows to a crawl and any executable that causes
disc access (i.e. it's not cached or reads config files etc). Won't
execute.

dmesg seems to work, but doesn't really show anything. After the
"stopping tasks" I get a weird "Back from C!" message, but that's
about it.

What could I try from here?

I tried the suspend patch offered on the Acer TM 800 page linked in
video.txt, but it did not make a difference.

Side note:
I'm sorry there is no patch attached to this email, or probably any
email in the near future. I am trying to work myself into the subject,
but - as you know - it's very hard. And asides from the ACPI specs,
there doesn't even seem to be a good document describing how it's
supposed to work and which elements have to be in which place for this
all to work.
However, I hope I can help debugging and contribute to your well
appreciated efforts at least a little bit. Hey, maybe one day I'll
even have a patch to attach - even if it only fixes a typo ;).

Thanks,
    Andre

I'd do it from text console, and insert printks just about everywhere
to see what is going on. See if disk is getting interrupts, for
example.
