Date: Tue, 17 Jun 2008 17:17:23 +0100 Message-ID: (sfid-20080617_181742_447297_198DA5E5) Mime-Version: 1.0 Content-Type: text/plain; charset=ISO-8859-1 Sender: linux-wireless-owner@vger.kernel.org List-ID: In the latest Linus kernel some kinds of connections over my wireless link have been hanging. By this I mean, for example: $ ssh [Wait a while] Connection reset by This also affects some http requests such as loading slashdot but not others (perhaps small ones?) such as twitter API http requests. It does not seem to affect connections to other machines on my LAN, only ones over the internet. I've tried tcpdumping to get more info but when I run tcpdump the connections work again (if a tiny bit slower). I've bisected this bug down to 608961a5eca8d3c6bd07172febc27b5559408c5d "mac80211: Use skb_header_cloned() on TX path." and naively reverting this change seems to make the bug go away. I'm using the rt2500pci module and wpa supplicant. My setup is: Laptop -- Wireless AP -- Router -- Cable Modem -- The Internet and my card is a "RaLink RT2500 802.11g Cardbus/mini-PCI (rev 01)". Please let me know if you need any more info or if there's a more focussed test case I could try. -- Andy Price
