"max_cstate=1" did the trick, the system is now much snappier, no pressing keys needed. Is this some BIOS option that I need to change, Jan? I'm using the defaults for this system, but I see settings such as

Enhanced SpeedStep y/n Enhanced Idle Power State y/n

Maybe worth trying (more likely for the latter than the former), but you never know what exactly hides behind those. In the end right now we only know there is an issue (perhaps interrupt signals getting lost) _somewhere_. Could be due to hardware, firmware, or software. So far no hypervisor log has been attached here, so I can't even judge which of the C-state drivers is being used. If it's the MWAIT one, suppressing its use and using the ACPI one would be another thing to try. If the latter works, precise CPU model information would be needed, along with indication whether the intel_idle driver in Linux doesn't cause such hick-ups. -- You are receiving this mail because: You are on the CC list for the bug.
