[Bug 528720] Re: Keyboard stuck with irqbalance

[L Schmiedl]

The same problem on my notebook Dell D830 with a docking station. I installed a fresh Ubuntu 10.04 tree weeks ago. Before I used Ubuntu 9.04 without problems.
Now I randomize get freezes on GDM Login. Both keyboards, internal and PC/2, also the synaptic touchpad and the external mouse are frozen. All other devices seems to be right. I can shut down the system with the power button and reboot. Or I can switch the external mouse and keyboard on a PS2-USB-Converter. After I plug-in this, I can log in and work mit the notebook.
After a reboot the fault is disappeared. Mouses and keyboards on PS/2 and internal devices works fine. The next freeze I get 3 or 4 days after.

In case of fault I found the following entries

[27.681159] input: PS/2 Generic Mouse as /devices/platform/i8042/serio1/input/input14
[27.881028] psmouse.c: Failed to enable mouse on isa0060/serio1

in /var/log/messages.

I tried the next hints I found in different discussions to thies topic,
but no result:

1. use option noapi on grub
2. change kernel from 2.6.32-23-generic-pae to 2.6.32-23-generic
3. change compiz to metacity
4. disable KMS
5. install mdetect
