It means that the kernel sent a command to the device, and never got an
interrupt back. This can happen on the IDE bus, which is not really
well protected to electrical problems.
Did you see it only once, or each time you boot your floppy on this machine ?
Can you use the disk after that ?
Also, the bio/net/ttymask looks weird to me ... What machine is it ?
