Well heres my first attempt at kernel debugging
the problem posted yesterday. I some magic sysrq-<P> on the 486 after the
Donald Becker eth0 message displayed. I had to hand write the EIP trace and then
enter it into ksysmoops. Don't know if it will help but I'll try recompiling the
kernel without any APM stuff and see what happens.
