I don't think it's the cable.  I started getting these recently as well
(starting about a week ago).  Always when there's a lot of CPU and disk
I/O load.

Also sometimes my USB keyboard would become unresponsive at about the
same time (under high load).  Sometimes it would stutter and act like
the key was being held down for a second or two.

I built a new kernel (6.2-PRE now) on 9/12.  The keyboard problem seems
to be gone but I still get the em watchdog timeouts occasionally.
