The same goes for (which can be easily rediffed against linux-2.6): [PATCH 06/12] rt2x00: Put 802.11 data on 4 byte boundary without it, at least rt61pci, rt73usb and rt2500usb (plain 2.6.24-rc7-git2) trigger the well known: WARNING: at net/mac80211/rx.c:1486 __ieee80211_rx() Pid: 0, comm: swapper Not tainted 2.6.24-rc7-git2-slh64-smp-1 #1 Call Trace: <IRQ> [<ffffffff80232e4a>] __wake_up_common+0x5a/0x90 [<ffffffff881fed9e>] :mac80211:__ieee80211_rx+0xbde/0xd00 [<ffffffff880cb3e6>] :ehci_hcd:ehci_work+0x5d6/0x8e0 [<ffffffff881f028b>] :mac80211:ieee80211_tasklet_handler+0xbb/0x120 [<ffffffff80243507>] tasklet_action+0x47/0xb0 [<ffffffff80243415>] __do_softirq+0x75/0xe0 [<ffffffff8020d62c>] call_softirq+0x1c/0x30 [<ffffffff8020f9f5>] do_softirq+0x35/0x90 [<ffffffff802432a6>] irq_exit+0x96/0xa0 [<ffffffff8020fad0>] do_IRQ+0x80/0x100 [<ffffffff8020af60>] default_idle+0x0/0x40 [<ffffffff8020af60>] default_idle+0x0/0x40 [<ffffffff8020c981>] ret_from_intr+0x0/0xa <EOI> [<ffffffff80220e60>] lapic_next_event+0x0/0x10 [<ffffffff8020af89>] default_idle+0x29/0x40 [<ffffffff8020b00f>] cpu_idle+0x6f/0xe0 > There are also a bunch of antenna selection fixes that never went > upstream.

I can just agree to this statement, rt73usb works really well (at steady ~2.4 MB/s) and rt61pci is the first driver to actually work at all (yes, the same performance issues, but rt61-legacy freezes using wpa2psk; rt2500usb seems to have more problems). All tests based on plain 2.6.24-rc7-git2 (amd64 and wpa2psk/ CCMP) + the following patches: - [PATCH 06/12] rt2x00: Put 802.11 data on 4 byte boundary - [PATCH] rt2x00: Corectly initialize rt2500usb MAC Thanks a lot Stefan Lippers-Hollmann - To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
