Re: Kernel Panic at boot with -CURRENT (last 2-3 days)

1999-08-19 Thread Poul-Henning Kamp


See my earlier post today, it is due to the PnP probe.

If you boot a kernel which is older than Mikes commit,
you can boot the new kernel after a soft reboot...

Background:

Work recently assigned me a Gateway GP7-500 (PIII-500mhz, 96M RAM) to
replace my older 333mhz PII that's been running FreeBSD 3.2.. Of course,
as my testing machine, I wanted to run FreeBSD 4.0-CURRENT on it, and
installed the 19990806 snapshot without a problem, and then cvsupped it
to -CURRENT. 

Problem:

This was on 17AUG, my kernel panic'd, I just assumed I left something
out, but then I saw that GENERIC panic'd as well, and has panic'd since
17AUG, and continues to do so with the -CURRENT snapshot of an hour
ago.  However, GENERIC from 19990806 works just fine. I decided that
after 3 days of kernel panics that it's a real problem and not just some
little -CURRENT breakage. 

I decided yesterday that maybe I need to make world first, so I did. No
dice there. And an hour ago, I also rm -Rf'd /usr/src, cvsupped to
-CURRENT, made world again, and attempted to rebuild the kernel.

Yes, I saw that, and tried to rebuild includes this morning (as per your
reply), and I still had a kernel panic. So I just went ahead and re-made
world, but that didn't seem to help things either. 

Just in case it had been fixed after I sent the initial post, I've
re-cvsupped, made the includes, and recompiled GENERIC to see if that
fixed it.. but it still remains an issue for me. Still get that panic
(though it is almost assuredly the problem, as the next event IS the PNP
probe).  

This is of course, assuming I'm not misunderstanding something.

This appears to be due to our PnP BIOS invocation not being 
sufficiently bug-compatible with some BIOSsen.  I'm going to need to do 
some more work on this, and if you have time I'd like to get you 
involved in the testing process.  

Meanwhile I'll be disabling the PnP BIOS scan which should get you back 
on the rails.
