Hi.

After reading Changelog for 2.6.6, I have seen b44 driver was updated,
and it should support new HP/compaq laptops now. I tried 2.6.6 kernel,
but I have a problem: b44 module does not work(TM).

System info:

Laptop compaq nx5000
kernel 2.6.6
gcc 3.2.3
binutils-2.14.90.0.4
module-init-tools 2.4.26

modprobe b44 and `ip link set dev eth0 up' gives this in dmesg:

Host pinging on network timeouts with icmp destination host
unreachable, pinging of my own address (on the nx5000 laptop) works,
lsmod always shows b44 is zero used, even when link is up and local
ping works. It is not possible to ping any other address on the link.
If I remove b44 from kernel eth0 dissapears, even if it has IP address
on it.

loaded modules: rtc and b44 (single user mode). Kernel is vanilla
2.6.6 from kernel.org.

Output from "/sbin/ip addr list" looks perfectly normal BTW. :-\

It works OK with 2.4.21 kernel and bcm4401 driver from broadcom
www site. It does not work with 2.6.5 in any way.
