Do other devices work after S3 resume with the updated kernel, such as
NIC?
Not sure if you are using vesafb. Somebody attached a patch at
http://bugzilla.kernel.org/show_bug.cgi?id=5351 to resolve the video
issue
for a Toshiba laptop. Maybe you can try.

Thanks,
Shaohua

I do not use framebuffer.
The laptop wakes up, only the lcd is blank.
I can execute commands (without seeing anythin, blind). I can start for 
example the ssh daemon an connect from an other pc to the laptop...

Re: s3 buggy after kernel-update

[Rathgeb Markus]

the important thing in my script are the following lines:

	statedir=/tmp
	/usr/bin/chvt 12
	/usr/sbin/vbetool vbestate save > $statedir/vbe
	/usr/bin/sync
	echo -n mem > /sys/power/state
	/usr/bin/sync
	/usr/sbin/vbetool post
	/tmp/radeon/boot-radeon
	/usr/sbin/vbetool vbestate restore < $statedir/vbe
	/usr/bin/chvt 7

with the kernel 2.6.12-gentoo-r10 it works fine.

with newer kernel for example 2.6.14-gentoo-r02 this do not work
i started without X
i conencted to my laptop AFTER wake up, to see the error messages...

when i execute
	/usr/sbin/vbetool post
or
	boot-radeon
from http://www.doesi.gmxhome.de/linux/tm800s3/s3.html

i get:
"Ungüliger Maschinenbefehl"
(in english, invalid machinecommand i guess)

and when i execute startx:
(EE) RADEON(0): No V_BIOS fount

s3 buggy after kernel-update

[Rathgeb Markus]

i own a 'targa traveller 811'. the company 'targa' supports only 
microsoft windows (who is suprised).
for a few month i spend a lot of time to get s3 working and since then i 
used suspend-to-ram with full satisfaction with kernel 2.6.12-gentoo-r10 
(kernel from gentoo-sources with my own configuration).
because of an update to version 2.6.14-gentoo-r2 the screen keeps blank 
/ black / off after wake up from s3. i changed nothing in the kernel 
confiuration (except the new functions - make oldconfig...).
where can be the problem?
does somebody know what could be responsible for this?

--------------

sorry for the bad english - i have done my best *g*

Look at Doc*/power/video.txt. If that fails... you probably need to
binary search for what broke it. Oh and try vanilla kernels...

Do you still recall what you did to get S3 working before?

Thanks,
