I'm sorry for flooding this thread, but I have more experience to share. After another reboot in "clocksource=jiffies" mode, I saw that 1 OS second passes in real 0.5 seconds. But the rest of the system was pretty stable. Keyboard auto-repeat was twice as fast, but did not get triggered inadvertently.
I did another reboot in "clocksource=jiffies" mode and opened the online clock application. Initially the clock speed seemed normal. After 20-30 seconds it became twice as fast. Then from the console, I started an application with an infinite loop therein. That made the clock seconds turn very very fast. Probably CPU speed has influence here. Good news is that when I changed the boot option to "clocksource=tsc", I got stable results even after a few reboots. Seconds seem to pass as fast as they should be. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/124406 Title: Keyboard keys get stuck and repeat Status in GNU Emacs: Invalid Status in Linux: Confirmed Status in X.Org X server: In Progress Status in linux package in Ubuntu: Won't Fix Status in xorg-server package in Ubuntu: Won't Fix Status in linux source package in Jaunty: Won't Fix Status in xorg-server source package in Jaunty: Invalid Status in Gentoo Linux: New Bug description: Keyboard keys such as the arrows, Alt-F4, PageUp/PageDown, etc. often get 'stuck' and continue being 'clicked' even after they are physically released. For example when clicking Alt-F4, sometimes it gets stuck so all the windows are closed instead of just one. My configuration is Feisty + Xgl + Compiz Fusion. My previous configuration was Edgy + Xgl + Beryl, where this didn't happen. Others have reported the same problem without using either Xgl or Compiz. The keyboard itself isn't the problem. When dual-booting to Windows, everything works fine. Also, the problem happens with two different keyboards (internal laptop, external USB). My best guess is that the problem occurs at time of high system load. Somehow during these times the key-release signal gets lost and the key-press is repeated indefinitely. This happens more often with Compiz configurations because Compiz tends to increase system load. It also happens more often with power-hungry apps like Firefox and Acrobat Reader for similar reasons. PS: When the keys would repeat all input devices would be locked up. ie. mouse won't move, clicks don't do anything, keyboard presses don't register. Then when it becomes unstuck, the mouse moves around and everything. Hope this helps.
