kernel: psmintr: out of sync

[Alex Wilkinson]

Hi all,

I am switching between several OS's with a Cybex KVW switch.

I now seem to have a problem with my mouse (after build world/kernel).

FreeBSD 5.1-CURRENT #2: Wed Aug 20 13:28:54 CST 2003

I am getting these messages on the console when I move my mouse, the cursor moves in a very
choppy motion (painfully slow).

Oct 1 09:46:17 squirm kernel: psmintr: out of sync (0000 != 0008).
Oct 1 09:46:17 squirm kernel: psmintr: discard a byte (1).
Oct 1 09:46:17 squirm kernel: psmintr: out of sync (0000 != 0008).

Oct 1 09:46:18 squirm kernel: psmintr: out of sync (0000 != 0008).
Oct 1 09:46:18 squirm kernel: psmintr: re-enable the mouse.
Oct 1 09:46:18 squirm kernel: psm: DISABLE_DEV return code:00fa
Oct 1 09:46:18 squirm kernel: psm: ENABLE_DEV return code:00fa
Oct 1 09:46:20 squirm kernel: psmintr: out of sync (0000 != 0008).

moused is running with the following:

"moused -p /dev/psm0 -t auto"

The mouse is a Microsoft IntelliMouse connected to the KVM via a USB->PS/2 adapter.

If I boot the same machine into -STABLE this does *not* happen.

I have tryed running moused with different protocols without any luck.

Can anyone help me solve this problem ?

I have to run -STABLE if I can't solve this problem, so any help would be appreciated.

Thanks

p.s the mouse works fine with: RH Linux, Irix 6.5.20, Tru64, and WinXP.

Switching the KVM while the mouse is sending data can cause this
behaviour. Better KVMs interpret the data sent by the mouse and delay
switches until a complete mouse output has been sent to the computer.
