OK, next guess..
The boot1 algorithm is quite simple:
int
main()
{
<..>
start = rpcc();
freq = ((struct rpb *)HWRPB_ADDR)->rpb_cc_freq;
while (((rpcc() - start) & 0xffffffff) < freq) {
twiddle();
if (ischar()) {
getfilename(filename, name);
name = filename;
break;
}
}
loadfile(name, loadaddr);
entry = (void (*)())loadaddr;
(*entry)();
So, what happens is that if there is a key press, getfilename() is
called. getfilename() is what produces the "Boot:" prompt.
So, I think that there may be some line noise on your serial console
line or keyboard cable which is interrupting the boot process. People
who've trashed their /boot/loader would probably pay money for such a
feature ;)
