I did the 4 files above manually and applied partial patch for the new files. When I load the module it seems to have succeeded once, but every insmod attempt I do now fails with following trace: Apr 11 16:43:43 arend-laptop kernel: [ 61.249239] axi-pci-bridge 0000:03:00.0: PCI INT A -> GSI 17 (level, low) -> IRQ 17 Apr 11 16:43:43 arend-laptop kernel: [ 61.249312] Core 0 found: ChipCommon (manuf 0x4BF, id 0x800, rev 0x22, class 0x0) Apr 11 16:43:43 arend-laptop kernel: [ 61.249339] Core 1 found: IEEE 802.11 (manuf 0x4BF, id 0x812, rev 0x17, class 0x0) Apr 11 16:43:43 arend-laptop kernel: [ 61.249400] Core 2 found: PCIe (manuf 0x4BF, id 0x820, rev 0x0F, class 0x0) Apr 11 16:43:43 arend-laptop kernel: [ 61.279913] Modules linked in: axi(+) binfmt_misc nouveau ttm drm_kms_helper drm i2c_algo_bit snd_hda_codec_hdmi snd_hda_codec_idt snd_hda_intel snd_hda_codec snd_seq_midi snd_hwdep ppdev snd_rawmidi snd_pcm snd_seq_midi_event parport_pc snd_seq snd_timer snd_seq_device lp pcmcia snd uvcvideo soundcore snd_page_alloc dell_laptop videodev dell_wmi dcdbas sparse_keymap intel_ips yenta_socket video pcmcia_rsrc pcmcia_core parport intel_agp intel_gtt agpgart psmouse btusb bluetooth joydev serio_raw usbhid hid mmc_block ahci sdhci_pci firewire_ohci sdhci e1000e firewire_core mmc_core libahci crc_itu_t Apr 11 16:43:43 arend-laptop kernel: [ 61.280052] Apr 11 16:43:43 arend-laptop kernel: [ 61.280366] Pid: 2008, comm: insmod Not tainted 2.6.39-rc1-staging-next-09270-gb905e26 #1 Dell Inc.
