Hello,
i ran into a similar problem when recently trying to install 8.0R on an
embedded system. We've been using this hardware for a couple of
years with FreeBSD 4.11 and didn't see any problem like this.
Disabling the memory hole (15-16M) solved the problem here, but
that shouldn't be a solution. I wonder whether it's a loader-, or a
BIOS-problem, since memory-allocation should respect reserved
areas.
Best regards

Grr, I double-checked how it got stuck, then I found the console
redirect was disabled because of an old device.hints. The revised
summary is:
loading text loading syms boot
1) OK OK OK
2a) "readin failed" - -
2b) OK "skipped!" OK
2c) OK "skipped!" OK
3a) OK OK OK
3b) OK OK OK
3c) OK OK OK
So, the case 2c shows that your patch solves the problem in the case
2a. Thank you! :)
Loading>8MB kernel works now, but loading syms sections still fails
even in the case 2c.
Ok. Your system's SMAP is kind of weird (it has a very small region above
1MB, so it may not deal well with "large" kernels, though I thought it had
enough room for at least a 12MB kernel. Hmm, the size of the kernel file may
be deceptive though since it does not include BSS. I wonder if it is trying
to load the symbols after the BSS.
