*Ouch*. In mpage_writepages()? This is pretty much in the very core
kernel near I/O page cache and file system, not somewhere near
networking. Both CTC device driver and all user space components like
Yast avert suspicion as far as I can tell.

Is there another message right before "illegal operation: 0001 [#1]"?
Probably one that says "kernel BUG" or "Ooops" or similar? Usually
kernel traps use illegal opcodes to crash the thing on purpose, but
they are supposed to print a useful message before that.

cheers,
Carsten
