after bisecting a bit, i'm puzzled because it seems ttyflags -a hangs only happen when a spurious com0 is found in dmesg: com0 at isa0 port 0x3f8/8 irq 4: ns16550a, 16 byte fifo com0: probed fifo depth: 0 bytes but that device isnt present in the working boots from various kernel versions (tried kernels from end of december to 1 feb so far) it's enough to test with boot -s and ttyflags -a, i think i triggered it once with a kernel from #1587: Sat Dec 30 22:44:51 MST 2023, next boots on the same kernel were okay.. I've tried differentiating cold boots vs reboots, but that didn't help. Landry
