With current b43 it still fails with Out of memory when using a recent firmware 666.2 and works with an old firmware 410.2160. I tried DMA and PIO mode and had the same results. I added some printk's into the code and implemented some parts b43 does not have but the Braodcom sdk and brcmsmac has in the dma code, but I haven't resolved the issue. I found out the error occurs when send some packages doing "ifconfig wlan0 up" does not result in any problems, but when I try to scan with "iw wlan0 scan" it oopes very soon. The problem seams to be related to TX as there are many packages received, but the oops occurs after 4 calls to b43_dma_tx() Larry, you wrote some more LP spec based on a newer driver is there a list with updated docs or should I manually look into all packages if I want to implement it like it is in the new wl driver. As I see there are also many parts not implemented, but described in the spec so looking over the hole code is probably needed. My device has a sprom of revision 3 and not the expected version 8, does this cause any trouble? Hauke.
