Ok I've personally tested the "notsc" option but it does not allow my system to boot. I'm using an AMD64 Turion cpu, single core. But, while searching a bit on the tsc, I found out an AMD engineer talking about TSC drifts and how to avoid them in Linux using the boot option "clock=pmtmr". However, that option is deprecated by "clocksource=acpi_pm". So I've successfully booted the system using that third boot option, and now my system time is not regulated by TSC :
[ 18.627549] Kernel command line: root=UUID=54ddb1ca-30a7-4ddd-b038-4915de74d9a3 ro quiet splash clocksource=acpi_pm [ 20.839908] Time: acpi_pm clocksource has been installed. My laptop is up since 30 minutes, and up to now, I did not encounter the repeat rate bug very often using the acpi_pm clocksource, but I did onnnnnnnce (now twice). Therefore I do not think TSC is the cause of this bug, although the problem subjectively seems to be less common using the acpi_pm clocksource. -- repeate rate problem, sometimes repeats character many times while typing. https://bugs.launchpad.net/bugs/92594 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
