NetBSD 1.5.1 (laptop) #1: Wed Oct 3 02:30:54 BST 2001
root@build:/usr/src/sys/arch/i386/compile/laptop
>Description:
CardBus is detected, but fails to initialize properly. This results
in the inability to use any CardBus functionality.
cbb0 and cbb1 report a bad Vcc and bail out.
There was some commented code in /sys/dev/pci/pccbb.c. I uncommented
it as it described the CardBus state I was encountering. However
this did not fix the problem. It simply allowed the boot to
progress further. The supported PCMCIA network card was still
not detected during boot up.
This is an unbranded laptop, it functions running windows and freebsd,
I believe the hardware is also present in some Dell laptops.
Here is the dmesg from the laptop, the kernel had the patch in
"fix to the problem" applied, with various verbose and diagnostic
options in the kernel:
