Yes it is udev (at least for the moment - running on NFS root and
concentrating on kernel stuff)

My problem was that I had _two_ udev rules invoking /lib/udev/firmware.sh
this resulted in a race between them and the kernel sometimes getting the
firmware for the previous request - hilarity ensued!

One of the rules (50-udev-default.rules) was from the upstream udev source
The other (udev.rules) was put there by openembedded.
Have reported this to the OE list.

With that sorted out it all seems to work fine - I haven't done any stress tests
yet though.

Thanks for your help

Cheers,
Martin
