consumption in some weird way, as suggested by that log. :-/ Also i'm
not sure why this fix is needed as there was working kernel revision
with the same driver and it looks like nobody's analised what change
actually introduced the regression.

Just to remember that 2.6.28 kernels have wifi issue too, I just got
that fso disabling the wifi interface:

Linux debian-gta02 2.6.28-20090105.git69b2aa26 #1 PREEMPT Tue Mar 3
20:22:28 UTC 2009 armv4tl GNU/Linux

The 99% of time I cannot reboot the device and have to remove batteries.
In my 1 year freerunner experience I may say that WiFi never worked
fine, of course I did not tryied every single kernel but all the
default shipped with shr/om/asu/fso and their feed updates.
Some considerations: the hardware is broken? there was no big effort
by OM to patch the driver?
This bugs is fixed in the latest kernel, but I still prensent in the
2.6.28
