>Description:

I originally installed 2.2.5-RELEASE on the above machine from CDROM
with no problems.  I then decided to upgrade it to 2.2.6.  After I
get part way into the process, the system panics and attempts a reboot.
This happens whether I attempt to use the upgrade procedure or a full
re-install.  I have tried downloading a new copy of the boot.flp file
and I have tried several different floppy disks.  I invariably get a
panic/reboot, although not always at the same point.  Since I never
get to the point in the install where it attempts to write things to
the disk, I can still boot and run the original 2.2.5 installation
and it seems to work just fine.  I was also able to boot and run an
old 2.2.5 install floppy.

>How-To-Repeat:

boot the install floppy?

Darned if I know....

 Hmmmm!  Can you tell me a little more about what kernel configuration
 changes you're making, if any, and the _farthest_ point in the
 installation you've gotten to without a reboot?  Thanks!

 I have tried it both with and without kernel configuration changes.
 When I do make changes I generally delete all the scsi controllers
 and all of the ethernet controllers.  I only do this so it won't
 try probing a bunch of stuff that I don't have.  The furthest I
 have ever gotten is the point where you select the distribution
 kits you want.  I would begin the process of selecting what I want
 loaded and then the system would die and reboot.  The earliest it
 has ever died is immediately after uncompressing the kernel.

 Hmmm.  That is very odd!  It's rare for a machine without hardware
 problems to just die at essentially random parts of the install, but
 that's what yours appears to be doing.  Since you say 2.2.5 runs just
 fine, I also can't really blame your hardware, but yeesh - it has all
 the hallmarks otherwise! :( Hmmmmmmmm.  Without more evidence to go
 on, or physical access to the hardware, I'm not sure I can really
 diagnose this one.

 That was pretty my assesment of the situation.  Since the machine
 installed and booted 2.2.5 with no problems I was fairly sure the
 hardware was ok.  I am going to try swapping out the memory and
 if that has no effect I am going to try moving the drive to another
 machine and try running the install from there.  Do you want me to
 report back on what my results are?

 Yes, please do!  I'd be very interested in at least narrowing this
 down if it turns out to indeed be a problem with FreeBSD.
