Welcome to kmdb
kmdb: unable to determine terminal type: assuming `vt100'
[0]> :c
(hard hang -- no further console output at all after continuing from
kmdb. Re-tested against the corrected build (post hv-config memsize
fix, see src/tlb_fix/2048/1up.hdesc history) -- this is a DIFFERENT
outcome than before the fix, which trapped with "ERROR: Last Trap:
Level 14 Interrupt" during unix module load, before kmdb even finished
loading. With the corrected 2048M, it now boots past that point and
hangs later instead, after continuing from kmdb. So unlike the other
re-tested cells, this one's failure mode did change with the memsize
fix.)
