Suspend2RAM Asus V6V

Suspend2RAM Asus V6V

[Johannes Engel]

Hello everyone listening!

Since my laptop does not wake up from suspend2RAM under Linux I want to
get rid of that problem. I hope someone can help me here.

My system:
Asus V6V (Pentium M 740, intel ICH6)
openSuSE 10.2
Kernel 2.6.21.1 vanilla (also tested with suspend2 patch), same symptoms
using original openSuSE kernel
suspend-0.50-6

Symptoms:
I tried the various options and combinations of s2ram also from init
level 1. The symptoms remain as follows:
The laptop goes down to suspend2ram, if it is suspended the power led
starts blinking as it is supposed to do.
Switching the laptop on again hitting the power button (other buttons do
not show any effect) the cdrom drive gets initialised, the harddisk led
gets switched on but the screen remains black and the laptop hangs
completely (no keystroke accepted, even not Magic SysRq keys).

Do you have any hint where I can start digging (DSDT, BIOS, drivers)?

Thank you in advance,

Johannes

I have the same problem, and tried to debug it with net console, with
minimal kernel configs, with init=/bin/bash, with all the combinations,
to no avail. I did submit a bug report to the resepctive bug tracker but
it looks like nobody is caring for this kind of stuff.

Best wishes

OK, I investigated further with the following result:
Bios 0401 works quite well.
BIOS >=1001 seems to introduce a bug: s2ram does not work any more.
Since I do not have a BIOS between 04 and 10 (especially 0602 or 0801a) I cannot test the versions inbetween. If someone can provide me one of these versions I will try to hunt down the error which possibly resides in the DSDT.

Greetings, Johannes

Well I have an Acer TM 3012, but with more or less the same hardware, so
I guess this won't help you. Could you dump and disassemble the two
DSDTs and compare them, maybe the difference between those also may be
found in the DSDT of the Acer.
