So, can this problem be solved like on below patch, or I should rather
split firmware loading into chunks similar like was already iwlwifi did?

Hmm, I looked at iwl3945 code and looks loading firmware in chunks is
nothing that can be easily done. 3945 bootstrap code expect that runtime
ucode will be placed in physically continue memory, and there are no
separate instructions for copy and for execute, just one to perform both
those actions. Maybe loading firmware in chunks can be done using
undocumented features of the device, but I'm eager to do this.

Just allocate memory during boot?

On driver I can reserve memory during module load, but also this isn't
something I prefer to do.

Pavel, do you still can reproduce this problem on released 3.6 ? 

It happened again yesterday on 3.6.0-rc6+. I don't think mm changed
between -rc6 and final...

Could you check  __GFP_REPEAT oneline patch posted previously ?
And if that fail again, provide full dmesg (on your previous messages
there is vmap() failure, which I do not understand, where it come
from) ?

Thanks
Stanislaw
