I get the same behaviour on RELENG_6 (kernel reports itself as
6.3-STABLE #4).

Do you think I should try with -CURRENT? Would that even work with a 6.3
userland, or would I need to build world as well?

I can also re-enable debug output in the isp driver and report what is
going on there. Unfortunately last time I tried this the two results
were not that useful: (1) capturing it from the screen (or Dell RAC
output) you only get the last 20-odd lines; or (2) redirecting to a
serial console slightly changes the behaviour (it still never boots but
remains forever in some kind of retry loop), perhaps because the kernel
execution is throttled to the 9600 baud output speed. Could try
115kbaud, but that is still pretty slow, relative to no serial.
