I think I've found the problem, but never seen a message like this before. This server also provides fax services via a USR Courier modem. The power for the modem was disconnected. So it appears the combination of hylafax starting on /dev/ttyS0 and the modem being unpowered resulted in the generation of the do_IRQ No irq handler for vector message. Sorry for the noise -- at least this was just the backup fax server... -- David C. Rankin, J.D.,P.E.
