I've seen the same kind of panic on my diskless MVII/3300 running make build
(still a.out - I'll switch to ELF when this is solved :)
More details:
My MVII has completed a make build running a 1.5ZA kernel (build from sources
supped March 4 or March 5 - I don't remmeber exactly). Once make build
was complete I upgraded kernel again from sources supped 2 days ago.
I attempted 3 make build, all 3 failed in different ways:
- first it got a segmentation fault in the kernel (sorry I don't have the
exact message, a network problem caused my ssh to time out not long
after)
- The second attempt hung at:
install -l s -r -o root -g wheel -m 755 usr/src/sys //sys
with a sh process spending all its time in kernel. A ktrace of the process
didn't show anything, it was really looping in the kernel without going
back to userland.
- Third attempt: the kernel paniced with:
extent `ptemap' (0x80bf3000 - 0x871b3000), flags = 0x3
I'm back running the 1.5ZA kernel for now :)
