[oe] libertas seems broken since udev 180

[Andreas Müller]

Hi,

this problem I face since a while but didn't find the time to take
care. Since udev 180 overo's wlan does not work (marvel) and  I get:

at early user space:

and cyclic ~every 3s

libertas_sdio mmc1:0001:1: wlan0: command 0x0000 timed out
libertas_sdio mmc1:0001:1: wlan0: Timeout submitting command 0x0000



With udev 175 wlan is working properly and I get after boot prompt
(please ignore 'Network Manager Wait Online'-lines. This is for test
and it looks same with unmodified networkmanager):

Any suggestions where to get further information on how to solve? Is
it possible that the changed sequence causes adapter not yet started
up when reading MAC / firmware info?

Thanks in advance
