This is a little weird, but some time ago I decided to play with
splash screen option, but it didn't work. The error message was
something to the effect of video mode not available. Well, before
recording the dmesg.boot I decided to comment out the splash
screen lines from loader.conf so the output would be a little
cleaner.
Now the warm boot lockup still occurs at isa0: BUT boot -v has
a few more lines after isa0: which WERE NOT there when the splash
screen stuff was in loader.conf. Included below is dmesg.boot
from a successful cold boot. The failed warm boot -v stopped
after displaying the line "Trying Read_Port at 3c3" 8 lines below
the "isa0:<ISA bus> on motherboard", just before displaying the
line "isa_probe_children: disabling PnP devices".
