I got two Oops'es with 1.3.27 while having an active Netscape session through
a CSLIP connection:

The network connection died, but the system was otherwise unaffected,
although I did reboot "just in case".

The system is an almost all-ELF system, kernel compiled with gcc 2.7.0,
libc 5.0.9. CSLIP compiled in, no other net-devices.
