Re: Was: More ULE bugs fixed. Is: Mouse problem?

I've had this problem on my laptop since I bought it last year and started
running -current.  It's annoying, but luckily doesn't happen very often.
My gut feeling here is that the psm driver isn't servicing its interrupts
fast enough and characters are being dropped out of the FIFO.  Maybe it's
time to take the psm driver to task and figure out how to make it fast.
