b43: Radio Hardware Status Disabled

b43: Radio Hardware Status Disabled

[Michael Larabel]

With a Linksys WUSB600N and NetGear WNDA3100, which both appear to 
utilize a Broadcom 4311 chipset, the radio hardware status always seems 
to get set to disabled immediately after the wireless interface is 
started and are never re-enabled.

This is happening with the b43 driver (found in Linux 2.6.25.3 kernel) 
on Fedora 9. Below is the dmesg and lspci output.

dmesg | grep b43

Anything to get these cards working?

Did you open a corresponding bug at bugzilla.redhat.com?  If not,
please do so (and CC: linville@redhat.com if you don't mind).

What is the latest F9 kernel you have tried?  Could you try one of
the latest ones from Koji?

The wireless bits in the freshly installed F9 kernels are a bit old,
so I want to make sure you are working with modern code.

Thanks!

John
