Under my 2.6.28-rc6 sparc64, when associating to an AP through my zd1211rw device, I was seeing kernel log messages like (not exact output): Kernel unaligned access at TPC[10129b68] zd_mac_rx+0x144/0x32c [zd1211rw] For the zd1211rw module, on RX, the 80211 packet will be located after the PLCP header in the skb data buffer. The PLCP header being 5 bytes long, the 80211 header will start unaligned from an aligned skb buffer. As per Documentation/unaligned-memory-access.txt, we must replace the not unaligned() safe compare_ether_addr() with memcmp() to protect architectures that require alignment.
