Has anybody had any success in the past few days getting an i386 kernel
to boot?  I've tried with sources updated on each of the last 3 days, to
no avail.  I tried building a GENERIC kernel today to verify that it wasn't
something specific to my kernel config, and that didn't work either.

All I get when I try to boot is the bootloader message (this from a custom
config; GENERIC does the same, but the numbers are different, of course):

  booting wd0a:netbsd - starting in 0
  2422950+35300+168700 [65+129968+94525]=0x2b9498
  [stops here after CRLF--no further output]

The currently working kernel is 1.5S from March 15, and I also successfully
booted the 1.5T GENERIC kernel from the April 7 snapshot.

The system is a pentium pro 200 (dmesg from April 7 snapshot kernel):
