Hi, As I see, one of the most active threaded callouts on idle VMware VM and some hardware is atkbd_timeout(), called 10 times per second. Plus it is also one of few remaining non-MP-safe callouts. According to the comment it seems to be only a workaround for some lost interrupts. That makes me thing: is it really needed to run so often and so accurate, or may be we could reduce it to 1-2 times per second? Or may be it can be avoided somehow 20 years later? -- Alexander Motin
