BeagleBone Black - 3.8.13-bone21.1 - strange timestamp in dprintk #31

susisstrolch commented 11 years ago

Tried to run my DVB Sky USB-Module with BBB and self compiled kernel. BBB hangs on heavily used USB (like this device) and shows back jumps in dprintk timestamps: Jun 20 17:33:19 arm kernel: [ 802.654332] dvbsky_usb: dvbsky_stream_ctrl() -off Jun 20 17:33:19 arm kernel: [ 803.375415] dvbsky_usb: dvbsky_stream_ctrl() -off Jun 20 17:33:20 arm kernel: [ 803.394597] dvbsky_usb: dvbsky_stream_ctrl() -on Jun 20 17:34:53 arm kernel: [ 718.350672] dvbsky_usb: dvbsky_stream_ctrl() -off Jun 20 17:34:53 arm kernel: [ 718.369438] dvbsky_usb: dvbsky_stream_ctrl() -off Jun 20 17:34:53 arm kernel: [ 718.382941] dvbsky_usb: dvbsky_stream_ctrl() -on

I wonder if it works on 3.8.13 with x86? The musb bus is still a little fragile with our v3.8.x based kernel..

Little searching found this patch: https://github.com/OpenELEC/OpenELEC.tv/blob/master/packages/linux/patches/3.8.13/linux-210-dvbsky.patch

Thats exactly the Patch I use. Btw this One Works absolute stable in RPi 3.8.13 and 3.9.7. it looks like some internal data gets overwritten on heavy USB usage.
