I don't know about SuperMicro mother boards, but I've seen this problem on
Dell PowerEdge servers (also P3). The problem in that case was caused by the
I/O APICs being incorrectly set up for the serial interface, so heavy serial
line usage eventually caused IRQ loss elsewhere (usually the aic7xxx driver
since it is the heaviest source of interrupts). Of course, when an IRQ is
lost, all bets are off for the driver. This sort of thing is usually an
MP-BIOS problem and was fixed (for the Dell) by upgrading to the latest
version of the motherboard BIOS.
