Would you provide some more details? Mouse model? What were you
doing when this happened? Do you use a KVM switch?
Would you test the following patch for sys/isa/psm.c? Please
apply the patch and add 'flags 0x10000' to psm0. Watch out for
error logs from psm0.
Note this patch is NOT the solution for this problem. But, rather
an interim workaround...
