A few months back, I tried upgrading one of my -Current machines to that
days code. Upon rebooting, the kernel bombs out right after the memory
detection with a page fault. I assumed the trouble was just in that days
snap, however I decided to try to boot off the boot floppy today. The
same thing happens, were it crashes right after detecting the memory. So,
it looks like there may be some sort of problem with the newer code
running on Compaq machines (at least my 4710 model) . I run -Current on
a few other machines which are not Compaq's and they work fine. I don't
have access to any other Compaq machines, or I would have tried it on
others to make sure it just wasn't my machine.
Currently, I am running a kernel from July 4th, which is working just
fine. When I upgraded, it was Sept 4th, which didn't fly. So, I believe
the problem has existed for a while as todays (Nov. 25) boot.flp gives the
same results.
Booting off the boot floppy gives these results right away after
the visual configuration screen ( I'm typing it is, so it may not be
exact) . BTW, the ram detection 8 megs off, but adding Maxmem into the
kernel config with the correct amount of ram reports the correct values.
I believe everyone already knows of that Compaq weirdness already.

Automatic reboot....
Booting with kernel -d doesn't give anymore information than that.
I am sure this has something to do with the unstandardness of Compaqs, but
am clueless as to how to get around this problem.
Here is my dmesg output running from my July kernel:
