Problems to get 4.6RC running on my laptlop

Hi all,


I work with FreeBSD 4.3 RC3 since a few months on my laptop. Now I
tried to make a update to 4.6, and...

...on the booting process FreeBSD crashes. Here is the output:


[...]
[to this point all looks good]

pci0: <unknown card> (vendor=0x1039, dev=0x7018) \
      at 1.4 irq 5

      at 1.6 irq 10

additional information:

Notebook Model     : Baycom Worldbook II
ATA Controller     : SiS 5591
PSI-ISA bridge     : SiS 85c503
Network controller : SiS 900
USB Controller     : SiS 5571


My first idea was, that there was something wrong, when I compiled the
kernel, but the 4.5 install cd rom produces the same panic.

Now I'm confused: Why does 4.3RC3 support my notebook chipsets, but
4.5+ produce a panic?

Does anyone has a idea why FreeBSD produce this panic?

And: What can I do? I have the 4.3 RC3 cd rom here, but this is not
what I want to do.


Any suggestions are welcome,

Andreas Zymny
