Hi,

I just tried the miniinst 5.2-BETA (kernel dated 11/25/03) on my
computer but it couldn't even boot. My mother board is a A7N8X Delux with
1Gb of main memory. It uses a NForce2 chip. The graphic card is _not_
embeded in the chip : I use an external GF2MX. The BIOS finds it on IRQ 11.
I wrote down by hand the last lines of the panic:

agp0: <NVIDIA nForce2 AGP Controler> mem 0xa0000000 - 0xbfffffff at dev 0.0=
 on pci0
panic: pmap_mapdev: couldn't alloc kernel virtual memory
cpuid 0;

And then to debugger :(.

I tried a 'where' command. Here are the latest functions called :
device_probe_and_attach
root_bus_configure
configure
mi_startup
begin

The panic also happens with the 12/03/03 ans 12/02/03 mini isos.=20
The same MB boots 4.9-Stable correctly.

I don't have a trace or boot -v log as I don't boot from serial. If it is
needed, I'm sure I can look into dusty drowers or ask a friend and get
a serial cable to do that.

I don't really know how to get more informations with a panic that early
in the boot process, but I'll gladly follow instructions.
