Dell i5100 resume from ram probl. (2.6.0-test11)

Dell i5100 resume from ram probl. (2.6.0-test11)

[Andreas J. Thorvaldsen]

I have run some tests with suspend-to-ram (S3) on my Dell Inspiron 5100
laptop (bios rev. A23, Radeon 7500, ps2-type keyb.), and these are the
symptoms I have encountered:

1. The display stays black after resume (text). If suspending/resuming
from X, some "scary" visual effects resembling "LCD hypothermia"
appears, followed by a dark (but backlit) screen. Typing commands on the 
keyboard gives no response.

2. echo 3 > /proc/acpi/sleep; sleep 10; reboot; does run, indicating
that at least one process resumes correctly.

3. A key logger (Linux Key Logger; userspace) stops logging after resume
(though /var/log/messages continues to write (no errors)), indicating
that it has died somehow (although ...; ps -A > dump; indicates that it 
hasn't).

What are the likely causes of this problem? Is it a timer-, interrupt-, 
keyb.-, or video-problem or a pure ACPI problem? Where should I start 
debugging? Any help og advice is greatly appreciated.

It's most probably your keyboard that has died, and not the keylogger. 
http://www.geocities.com/dt_or/input/ should address that (against vanilla
test11).

Unfortunately, you will probably be needing more than just that to properly
use S3... good luck!
