>Description:
I've been discussing my issue on netbsd-users here:
http://mail-index.netbsd.org/netbsd-users/2021/01/18/msg026437.html

amd64, Dell Precision WorkStation T3500, raidframe active

upgraded my home sever/gateway/firewall/nat from 8_Stable to 
9_Stable including adding ipf support to the kernel... everything 
seems to work except that the secondary bootloader /boot 
generated for n9 (both my self-compiled and binaries from 
the 9.1 release) are not being run from the first stage 
bootloader. I have verified that the new 1st stage bootloader 
is where the system hangs. If I switch /boot back to a binary 
from 8.1/8_Stable all is well, but the new /boot from 9+ just 
hangs.

Here are some details from a recent post to the thread above:
Below are a few other diagnostics I have tried in case they help
anyone else understand my issue...

# installboot -v -n -e /dev/wd0a

[NOTE: this was the most recent step I took to alter the 
1st stage bootloader to print a unique string just so I could 
be sure this was in fact the new 1st stage bootloader that 
was running]

>How-To-Repeat:
AFAIK, this only happens on my machine or others would be reporting it.

On my machine, all I need to do to turn it on is put a 9+ /boot in and turn it off with an 8+ /boot.
>Fix:
Only fix is to drop back to a /boot from 8+ and/or boot from a CD and use the 2nd stage bootloader from that to invoke my kernel
