keyboard not working after resume from suspend to ram (hp nx7400)

[maslokm]

Feisty Fawn Herd 3

After resume from s3 keyboard doesn't work on HP NX 7400 (ey508es, core duo).

In Edgy Eft to have working keyboard i needed to add line:

OnResume 20 bash -c 'echo -n reconnect > /sys/bus/serio/devices/serio0/drvctl'

to /etc/hibernate/ram.conf, and everything was OK, in Feisty Fawn with or without this line keyboard doesn't work. There is no any warning or error in dmesg.

Keyboard work with compiled swsusp 0.5 (Userspace SW Suspend).

Thanks for reporting this bug. To make any progress with it, some more information will be needed. Please add (by commenting on the bug) to the bug report the output of the following commands: 'uname -a' 'sudo lspci -vvn' 'sudo dmidecode' 'dmesg'. It would also be helpful if you could try to hibernate/suspend and after that fails, restart your system and attach /var/log/kern.log.0 as well. Thanks again for your contribution.

Same problem with notebook Fujitsu-Siemens Amilo PRO V3505 and Kubuntu Feisty Herd 4.

Hi!

This can be handled by compiling i8042 driver as a module and unload it at suspend and reload it at resume. It would be good if default kernel would have this driver as a module.

Hi,

Compiling the i8042 driver as a module solves the problem on my laptop (HP NX7400 - ey508es). There's another problem right now. The screen stays black after resume. Pressing the brightness keys on the laptop turns it back on.

Hi.

I have Compaq nx7300 and the same problem!

I installed yesterday official Ubuntu Feisty Fawn (7.04).

Will there be some patch or via new kernel update that fixes this problem?

Can you also explain how can you compile i8042 as a module if it is already inside the kernel? Does that mean that I need to recompile the whole kernel?

Beginning with the Hardy Heron 8.04 development cycle, all open Ubuntu kernel bugs need to be reported against the "linux" kernel package. We are automatically migrating this bug to the new "linux" package. However, development has already began for the upcoming Intrepid Ibex 8.10 release. It would be helpful if you could test the upcoming release and verify if this is still an issue - http://www.ubuntu.com/testing . If the issue still exists, please update this report by changing the Status of the "linux" task from "Incomplete" to "New". We appreciate your patience and understanding as we make this transition. Thanks!
