Yep.  It looks like a timing problem.  Perhaps the time your disks
need to ``settle'' is rather large, and by artificially defering the
disk probe (by entering UserConfig), you get the probe to succeed.

You could try to look into /sys/i386/isa/wd.c, into the function
wdprobe(), and try if bumping the timeout numbers or loop counters
will be of any help.
