I just made a current uvm/pmap_new bootfloppy (cheating a bit to get
vi on). It boots up an old 486 with no problems at all, but a cyrix
200mmx begins to boot, finds netbsd.gz, prints up the first number
(after the /|\/ sequence), then reboots itself and so on.

Any thoughts on how I could get a better idea of what is wrong?

Cheers,

Patrick


BTW, some random kernel options:
#options        I386_CPU
options         I486_CPU
options         I586_CPU
options         I686_CPU
