Hi Manuel,
Thanks for the instructions. The trace command says curlwp NULL, which =
I assume means that the kernel is crashing on a null pointer. Nothing =
suspicious in the dmesg output. The last enry in dmesg is "root file =
system is ffs". =20
I searched for curlwp NULL in the netbsd mailing list and the prognosis =
does not look good, looks like it's an unrecoverable kernel error. I'm =
wiping the disk with fx right now and will try a clean install of netbsd =
and see where I end up.
Chris

This is the kernel debugger. At this prompt type 'dmesg' (look at the =
last
few lines) and 'tr'; maybe this will give a hint at what's going on.
