I have been compiling kernels on all the machines I have access to
the last 4 days and I still havn't been able to reproduce the problem.
Please every body that has the problem, take time to examine and answer
as many as possible of these questions:
1. Do you see any output on the screen at all before the reboot ?
2. Does the precense/absence of "options DDB" change it ?
3. Does the precense/absence of "options BOUNCE_BUFFER" change it ?
4. how much ram do you have ?
5. what cpu do you have
6. which "cpu" lines do you have active ? ("I386_CPU" .. "I686_CPU")
7. With DDB, can you boot -d ?
8. How old are your bootblocks approx ?
9. try this patch to locore.s:

10. which console driver do you use ? syscons or pcvt ?
11. Does the precense/absence of "options PROCFS" change it ?
12. Does the precense/absence of "options NFS" change it ?
13. any other observations ?
