8.0-RELEASE install freezes

Sat May 1 02:40:12 UTC 2010

Hi,

I have an ancient Pentium II 350Mhz system that I've used as a home 
firewall for several years.  I decided to try to upgrade it from 6.1 to 
8.0 today, but I was unable to get the kernel to boot without freezing.  
The point at which it froze was:

vga0: <Generic ISA VGA> at port 0x3c0-0x3df iomem 0xa0000-0xbffff on isa0

Thinking it may be some ACPI related issue, I tried disabling ACPI in 
the kernel and from the boot prompt, but still no joy.  I also tried 
fiddling with the PnP BIOS settings with no luck.  Placing system into 
verbose logging mode, it gets as far as printing out:

Device configuration finished.
procfs registered

And then freezes, right before it normally displays the "Timecounters 
tick every xxx msec" line.

I have attached the full dmesg from the working 6.1 system.  I know it's 
a shot in the dark, but does anyone have any ideas or suggestions as to 
what I could do to try to get this thing to boot?  I've gotten many 
years of service out of this system, but I'd still like to squeeze out a 
few more.  :)

Thanks,
Steve
