To summarize, a -current i386 GENERIC kernel built today hangs during boot.
On a HP Vectra XU (on which a 7/31 kernel works just great):
It hangs this after the line starting "biomask ..."
It still hangs after removing lpt* and sb* from the config and disabling
the parallel port from the BIOS.
The same kernel (-current as of today, GENERIC) was tried an a 486/66
(Tangent computer) on which I have been running my production
Laboratory (currently at 1.2). It hung even earlier in the process.
It hung after printing "isa0 at mainbus0". The dmesg for this machine
from 1.2 is:
