Hello Josef, unfortunately I still have no possibility to get LOG output via serial, I only can print the LOG to screen and I'm too lazy to type the full log ;). However, I did some investigation into the problem. The device is stopped because of this error:
> dma_map_single: virtual address b008a78 not registered for DMA, called from: 1070bfc > def_error: Error sending BT_CONFIG: enqueu_hcmd failed: -12 Where dma_map_single is called by enqueu_hcmd. So the problem is related to DMA, Btw, I also tried to increase the memory quota to ensure there is enough memory. Ask if you need any more info from the logs, then I will type or do a photo) Cheers Christian On Monday 01 December 2014 16:50:14 Josef Söntgen wrote: > Hallo Christian, > > On 12/01/14 16:32, Christian Menard wrote: > > I'm experimenting with the new iwlwifi driver on a device with 7260 card. > > I > > enabled support for this card as mentioned in the release notes and added > > the corresponding firmware file iwlwifi-7260-8.ucode.
