This same card works on an x86 and on this wl500gp (bcm4704) w/ asus
code. If I flash the same image on a bcm5352 (whr-hp-g54), the driver
loads, the firmware loads and I get scan results.
Both the x86 and the wl500gp used the same ssb code and b43 code and
firmware. I'm using yesterday's wireless-testing.
The first oops was in b43/main.c:b43_phy_versioning at the read from
B43_MMIO_RADIO_DATA_HIGH. I used logic similar to that used for the 4317
to set the radio info to what I got from the x86 and got a little further.
The second oops was at ssb/main.c:1034 at the read from SSB_IDLOW. The
output is attached.
Any idea why some of these reads give bus errors?
