So far I think that this is the weirdest problem I've had with any
FreeBSD box.
I've just recompiled a kernel for this laptop (old Compaq Armada 1550)
which is a P133 with 16Mb of RAM. (Stop laughing you at the back!)
This is running 4.7-RELEASE.
Anyway, it's a reasonably cut down kernel which was all working fine
until I added options SC_PIXEL_MODE to the kernel. (This is because
the 100x37 VESA_800x600 mode is nicer than 80x25)
Now it hangs straight after finding sbc/pcm devices and right before
where it would normally find the hard disk (ad0).
The kernel IS NOT compiled with any userconfig stuff at all, however
if I boot from either BTX with -c or the loader with boot -c then it
boots up fine. I'm typing this in 100x37 mode on this very laptop
after two sucessful boots through the -c madness. Without the -c it
just hangs.
I'd include an output for debugging but I can't get any easily (no
spare serial leads). I can compile a kernel with the debugger and try
and find out a little more about where it's hanging but there is
someone about who has the faintest idea what is going on without me
trying to boot a debugging kernel on this slightly ageing machine then
that would be a better start. (ctrl-alt-escape does at least tell me
that there is no debugger in the kernel, but I know it's not really
getting much further because pccardd and perhaps init and whatnot are
not starting up and a power-off doesn't result in anything telling me
I'd not unmounted.. So I don't think it got that far.)
(I almost posted this to -questions, so feel free to flame me for
asking something that's prolly been round the lists before but which I
didn't find.)
Many thanks in advance,
