--- Comment #24 from Edward Tomasz Napierala <trasz@FreeBSD.org> ---
I wonder if the problem here isn't the command timing out itself, but the way
the driver spins on DELAY(9) for 100ms (1/10 of a second) to wait for its
completion.  Can't easily turn it into a sleepable msleep(9) because of the
locks held.
