Hi!
I'm trying to get the latest p54 wireless drivers (ad-hoc mode)
to work on a Nokia N810... So far, without any success.
Some words about my scenario:
- Nokia N810 running a custom omap1 kernel
(linux-omap-2.6.git / tag: "v2.6.29-omap1")
Patched keyboard (board-n800.c) and usb driver (usb-tusb6010.c)
to get it working...
- Installed Mer (Ubuntu 9.04) on an external mmc 4GB card
Patched the bootmenu stuff to get rid of static /dev/ nodes problem
which come up with the new kernel...
- compiled compat wireless drivers 2009-07-09
disabled CONFIG_RFKILL_BACKPORT_LEDS because it didn't compile
- A second N810 running debian and nokias 2.6.21er kernel
Ad-hoc mode is active. (ad-hoc is working, tested with some
other N810 devices)
After all these preparations, patching and workaround stuff,
i finally inserted the wireless modules into the kernel
(rfkill_backport, cfg80211, mac80211, p54common, p54spi)
dmesg looks fine so far:

After this short test, i switched the driver into ad-hoc mode,
setup the essid, channel and assigned an ip address... I tried
to ping, tcpdump, whatsoever... nothing happens. Driver statistics
are also frozen (in monitor mode the rx stats incr.).
The only hints to the problem are:
- this repeating kernel msg:
