- Turn off screen saver
- Do not start X
- Configure magic sysreq support.

If it locked up without oops, press sysreq-q.

The only known to today bug, which could (in theory) cause it is in
rt_run_flush() in route.c:

if ((rth = xchg(&rt_hash_table[i], NULL)) == NULL)
continue;

+ synchronize_bh();

for (; rth; rth=next) {

Also, try to comment out all the content of ipv4_negative_advice()
except for "return dst".
