The same USB keyboard is working correctly with Clevo D410J laptop with 2.6.28, so I guess it might be an USB problem.

Dmesg shows no errors. Please post /proc/bus/usb/devices of 2.6.28 (usbfs must be mounted) Regards Oliver

Created attachment 19603 [details] halfway on git bisecting Attached the "git bisect log" which contains the halfway results of git bisecting this problem. As I am having currently some bad block problems with the SSD drive I cannot continue bisecting until the bad block problem is solved. I publish the current log hoping it can bring us closer to the solution.

having a similar problem with a ibm/lenovo t60 hanging on a dock with a usb-keyboard (logitech) and dm-crypt. external keyboard works with grub, doesn't work with the password-prompt for the encrypted lvm and works again after some seconds of booting. everything worked fine with 2.6.27 (and does still work when i boot the old kernel) but not with 2.6.28 and 2.6.28.1. kernel built with debian lenny and make-kpkg. here are 2 similar problems, the second in german: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/310460 http://www.sidux.com/PNphpBB2-viewtopic-t-14236.html
All USB bugs should be sent to the linux-usb@vger.kernel.org mailing list, and not entered into bugzilla. Please bring this issue up there, if it is still a problem in the latest kernel release.
