We are also seeing this problem on an Acer Travelmate 4000 with kernel 2.6.15-26-686 (2.6.15-26.45).
Repeatedly querying the battery status like below causes most key presses to be lost (about 1 in 10 works) and makes the mouse move in a jerky way: $ while :; do cat /proc/acpi/battery/BAT0/state; done Adding "i8042.nomux=1" to kernel cmdline made no noticable difference. -- Keyboard random repeat https://launchpad.net/bugs/39315 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
