I can't recall exactly what the problem is (something related to interrupts AFAIR), but the effect is that you will see the system hang if you don't disable USB on Dell PE1850's. I haven't had a problem since I disabled USB. The problem has been discussed several times in the past on the FreeBSD lists. --=20 Simon L.
