Hello group, I managed to get AP with my bcm4306 rev 2 running using b43legacy and hostapd. I'm using compat-wireless-2009-11-13 with patches from openwrt trunk for my b43legacy driver. I use libnl HEAD version und hostapd 0.6.9. Now I have two issues. 1) I'm using Miktorik RB/14 4miniPCI =

Michael, I now have MMIO traces after modprobe of wl and b43, both after a fresh cold reboot. There are many similaries (of course), but some differences that could be important in the DMA errors. In both dumps, I see the code advancing through the cores. I don't see the PCI configuration
