Hello,
this is a bug report for SuSE-8.1, featuring a 2.4.19 variant of the kernel. Maybe it's
interesting anyway. When contacting SuSE, you might refer to SuSE's bug #22913...

When trying to run a DOS device driver for a serial device in DOSEMU
1.0.2, the dosemu process unexpectedly died (obviously when loading
the device driver). Only later I dicovered that a kernel oops was
generated every time as well. Here is the OOPS:
