    I've noticed this to some degree on the production version and worse it seems on the new beta. Sometimes when booting Linux under an XP host, the keyboard repeats very fast. With some careful work, I've been able to log in and things like e-mail programs time out immediately, so it looks like the timer is not being calibrated or is running very fast. Then sometimes it boots up and it is fine.

    Any ideas?

    A little more data. Right now it is fine and the dmesg log says:

    Calibrating delay using timer specific routine.. 4607.64 BogoMIPS (lpj=2303822)

    An earlier run says:
    Calibrating delay using timer specific routine.. 2029.45 BogoMIPS (lpj=1014726)

    And then:
    Calibrating delay using timer specific routine.. 2890.69 BogoMIPS (lpj=1445349)

    Both of these were bad.

    So it appears that the kernel's loop calibrator is getting something confusing and that's causing the problem. Still don't know how to fix it...

    This appears to only show up when you have hardware accelleration turned on. If I leave acceleration at high, it appears to be OK. The CPU is a AMD3800+ X2.

    Just for the record, this is still a problem in the latest RC.

    That seems to do the trick. However, kdm crashes a few times and then gdm gets started automatically, but that's not a big deal. Funny that kdm works ok without hw accel though.

    Thanks!
