It was never a real problem, just annoying messages. The hang is unrelated. Back out /sys/i386/i386/intr_machdep.c V1.6. It involves moving two lines of code. That will cure the hang. Combine that with an updated kernel and the messages should be gone, too. -- R. Kevin Oberman, Network Engineer Energy Sciences Network (ESnet) Ernest O.
