Miller" CC: wireless , LKML Subject: p54usb broken by commit b19fa1f Content-Type: text/plain; charset=ISO-8859-1; format=flowed Content-Transfer-Encoding: 7bit Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org Content-Length: 1143 Lines: 29 In testing 2.6.27-rc1, I found that p54usb caused my machine to freeze. A few times, I was able to use the KDE system status applet to see that the system was using essentially 100% of the CPU's. One other time, the system responded a little - enough for me to see tha wpa_supplicant was consuming 100% of the my AMD Turion 64 X2 running an x86_64 kernel. From bisection, the problem is due to commit b19fa1fa91845234961c64dbd564671aa7c0fd27 Author: David S. Miller Date: Tue Jul 8 23:14:24 2008 -0700 net: Delete NETDEVICES_MULTIQUEUE kconfig option. Multiple TX queue support is a core networking feature. Signed-off-by: David S. Miller Obviously, something in the driver cannot handle multiqueues, but I have not found anything, and I have not been able to get any logged events that show what is going wrong.
