I've been observing this happen once a week across a wide range of x86 systems with USB keyboards in the last (5?) years.
Since I've observed it in the virtual terminal and have never observed this with PS/2 keyboards, I suspect there is an event race condition in the USB input stack, eg a missing write barrier. When I increase system latency, it looks like there's more chance of it happening, so this feels like MMIO write ordering causing a lost key up event. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/124406 Title: Keyboard keys get stuck and repeat To manage notifications about this bug go to: https://bugs.launchpad.net/emacs/+bug/124406/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
