Samuel It was really wrong try, you cannot just leave place where firmware updated read pointer unallocated. I would rather focus on differences introduced by this patch. commit 738910c064ff461051cd37e17199f270ff88a9a3 iwl3945: use rx queue management infrastructure from iwlcore is the first to trigger the BUG_ON. However, prior versions would dereference a NULL pointer before the driver could get far enough to trigger the BUG_ON.
