i686, egcs-19991013, binutils-2.9.5.0.16
Booted 2.3.22 init=/bin/bash (2.3.22pre[12] hang on me in loadkeys). showTasks shows many modprobes running (???). Running ps(1) crashes for no /proc. Mount /proc, run ps(1) again and get:
Kernel bug at sched.c:573 invalid operand 000
After that, hard hang. Copied Oops by hand and run through ksymoops:
