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?
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...
