The machine is a P200, 64M, with two ISA 10Mb Ethernet adapters.
SysRq was not compiled since it is (minorly) broken in 2.3.21.
Shortly after doing "ifdown eth0" (the RH method for ifconfig down),
the machine crashed. I believe, from the ksymoops trace, that it was
while unloading the 8390.o module.
The Ethernet cards are:
ne.c:v1.10 9/23/94 Donald Becker (becker@cesdis.gsfc.nasa.gov)
NE*000 ethercard probe at 0x300: 00 00 e8 d2 12 8d
eth0: NE2000 found at 0x300, using IRQ 15.
eth1: 3c509 at 0x320 tag 1, AUI port, address 00 60 8c c0 c8 fc, IRQ 10.
3c509.c:1.16 (2.2) 2/3/98 becker@cesdis.gsfc.nasa.gov.
eth1: Setting Rx mode to 1 addresses.
Modules I usually have loaded are:
