REGRESSION NOTE: this is a re-test against the corrected build (post
hv-config memsize fix, see src/tlb_fix/2048/1up.hdesc history). Before
the fix, this exact image PASSED against tlb_fix/2048, reaching the
installer's "Select a Language" menu cleanly. With the corrected 2048M
memsize, it now traps (Level 14 Interrupt) during unix module load,
before kmdb even starts -- a genuine regression caused by the memory
config correction, not an unrelated pre-existing issue like the other
re-tested cells so far. Worth its own investigation.
