Hi all

recently I repaced my broadcom wireless card with a atheros one, so I flashed the kamikaze 7.9 of brcm47xx-2.6 image on my router.
However I got many warnings in the syslog saying "b44: eth1: BUG!  Timeout waiting for bit 80000000 of register 428 to clear." I searched the forum and found someone has met with this but I didn't find solutions.

Here is my dmesg:

IIRC 7.09 has problems with Atheros wireless cards. Compile latest trunk by yourself and try again.

this bug has nothing to do with the wifi card.  it's a known old bug, someone did fix it some time ago, but it reappeared on newer kernels.

@acoul
It seems no progress made out recently. Maybe wait for 8.08

be careful though I have 3 atheros cards that don't work with the atheros driver, the last is a 5006x (not the 5006xs which does work)

The discussion might have continued from here.
