My loader still doesn't boot on my Miata. :( It hangs claiming that it executed
the HALT instruction (not that it actually died with a stack fault like before
though):
...
Loading /boot/loader

halted CPU 0
halt code = 5
HALT instruction executed
PC = 2000a0c0

I can't get the most recent boot1 installed because disklabel
claims that it doesn't have space to write boot1 (?!)

000000002000a0c0 T extend_heap
000000002000a160 T main
Looks like it is dying right at the beginning of extend_heap:
000000002000a0c0 <extend_heap>:
2000a0c0: 00 10 3f 24 ldah t0,4096(zero)
2000a0c4: 04 04 ff 47 clr t3
2000a0c8: c8 00 41 a4 ldq t1,200(t0)
2000a0cc: 02 04 41 40 addq t1,t0,t1
Hope this helps...
