Latest kernel panic under 1.2.13. Keyboard VC switching still worked but
otherwise Linux was dead. Nothing in the logs to indicate any kind of
problem. The panic didn't get syslogged, so I had to write down the
screen and type it in by hand. Hope someone appreciates it!
Hardware:
486DX4/100, 40mb RAM
3c509 0x360 IRQ 5
The crash is in tcp_rcv() of tcp.c.
