Description Olof Wolgast 2007-01-21 04:49:47 UTC

Most recent kernel where this bug did *NOT* occur: Unknown
Distribution: Debian unstable

Hardware Environment:
HP NC8230 notebook

Problem Description:

Fails to wake up after S3 power down. It powers down correctly. When pushing the
button to power up, the fans go on, it reads from the HD for approx 10 seconds
but that's it. Commands such as "reboot" doesn't work, so it isn't a video problem.

S3 suspend works correctly under Windows XP.

I've tried to remove modules for sound, usb etc before suspending, also using a
plain text console without any X active, but no success. I'm eager to resolve
this issue, and I am an embedded real-time developer by profession, so I might
be able to help with some guidance.

Steps to reproduce:
echo mem > /sys/power/state

Please try the beep code at bug# 7860 to see how far the S3 resume could get.

Comment 7 Olof Wolgast 2007-01-23 13:06:25 UTC

I've modified wakeup.S so that the start looks like the code at the end of this
comment. The computer doesn't beep when woken up. I'm not too familiar with
x86-assembler, so I might have done something wrong.

I actually don't know if my laptop is equipped with a PC-speaker (how does one
check?, beep in ncurses doesn't work) but Windows XP reports a "System speaker"
device.

Comment 8 Len Brown 2007-09-06 15:38:15 UTC

Still a problem with linux-2.6.22.stable or later?

Comment 9 Olof Wolgast 2007-09-07 23:34:33 UTC

Can't tell.

I downloaded and compiled 2.6.22.6 (latest stable), but that one didn't boot. Used the .config from my old kernel (2.6.20-16, ubuntu fiesty fawn generic) when compiling the new one.

Starting up...

Comment 10 Olof Wolgast 2007-09-14 09:05:33 UTC

Yes, still a problem. I've resolved my general problems with 2.6.22.6, but the wakeup still doesn't work.

Comment 11 Rafael J. Wysocki 2007-09-23 03:02:19 UTC

It looks like s2ram might help you (http://en.opensuse.org/s2ram).  Can you please try it?

Comment 12 Olof Wolgast 2007-09-23 12:40:06 UTC

Yes, that worked right out of the box.
