Hi, I am having ethernet performance issue on panda rev A3. TX gets stuck while RX seems fine. At least pinging is ok... I started a thread on various mailing-list (http://comments.gmane.org/gmane.linux.network/234335). I made a lot of trials but no luck so far...
My problem may be related to the one described here for usb storage. My kernel already embeds Ming Lei's patch (https://patchwork.kernel.org/patch/1113332/), and CONFIG_ARM_DMA_MEM_BUFFERABLE and CONFIG_ARCH_HAS_BARRIERS are enabled. But still ethernet performance is really poor. Smsc9514 device driver relies on usbnet. I lack usb knowledge, thus I cannot state whether Ming Lei's patch in ehci-q.c "should" fix my issue if they were related. Otherwise, did anyone find out that CONFIG_PL310_ERRATA_769419 patch above effectively fixes the usb storage issue? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/709245 Title: ARM SMP scheduler performance bug To manage notifications about this bug go to: https://bugs.launchpad.net/linaro-ubuntu/+bug/709245/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
