Does this happen with the original redhat kernel? Strange, as far as I
can tell (from the kernel sources) SNDCTL_TMR_TIMEBASE is an OSS ioctl
(and /dev/ttyS0 is not a sound device... weird...). Maybe the pilot
software is trying to make a "beep" or something like that and is
pointing to the wrong device?
