John,

If possible, I would like you to do one more test on that troublesome netbook.
Please build a kernel with CONFIG_MMIOTRACE=y and build the Broadcom wl driver
for it. Starting with wl unloaded, issue the following commands (as root):

echo 10000 > /sys/kernel/debug/tracing/buffer_size_kb
echo mmiotrace > /sys/kernel/debug/tracing/current_tracer
cat /sys/kernel/debug/tracing/trace_pipe > wl_dump.txt &
modprobe -v wl

After the wireless network device gets created, etc., then

echo nop > /sys/kernel/debug/tracing/current_tracer
sleep 1
killproc cat

and send me the file wl_dump.txt. With it, I will be able to see if the Broadcom
driver is actually finding an SPROM that b43 is missing.

Thanks,

Larry
