Description Michael Meskes 2006-11-20 04:59:47 UTC
Distribution: Debian Sid
Hardware Environment: HP NX 7400
Software Environment: 
Problem Description: After resuming from suspend2ram (s2ram -p) my machine is
keyboard less. I have to "echo -n reconnect >
/sys/bus/serio/drivers/atkbd/serio0/drvctl" automaticaly to use it again. This
happens with a stock 2.6.19-rc5 but also with the Debian package of 2.6.18. 

I'm not sure where the problem exactly is, so maybe the category is incorrect.

What additional infos do you need?

Please do "echo 1 > /sys/modules/i8042/parameters/debug" before suspending and 
send me dmesg. Thank you!

dmesg after setting debug option

Here's the dmesg. I set the debug option, then suspended via "powersave -u" and
reset it again.

Hmm, can't quite see what is going on from the log as it is too short. Could 
you please recomplie with CONFIG_PRINTK_TIME=y and also boot 
with "log_buf_len=131072" and repeat the process. Also if you could put a delay 
in your script before forcing atkbd reconnect and bang on the keyboard a few 
times while it is not reconnected that would be great.

New extended dmesg

Hopefully this contains the information you need. I did as you asked and hit
the keyboard quite some time before calling reconnect.

BTW. since this bug is marked "rejected duplicate" I wonder if it's correct to
still report here.

Yes, it is. I will review the dmesg hopefully later tonight.
