NEC laptop ok with 4.9 but not run with 5.2.1

[Antoni Font]

Hi list,

I installed freebsd 4.9 on  NEC versa M500 laptop without problems.
Now I'm trying install freebsd 5.2.1 over the same computer but it not
run. Before the start-up options (I tried all types of boot, default,
with acpi......) and the cpu type and memory are detected, it remains
eternally stopped at the line:

pci_cfgintr: 0:2 INTA BIOS irq 10

I tried disabling sound card and other devices in the bios, but I have
the same error.

some suggestion?

Thanks in advance for yor help
