Also tested with kernel 2.6.31-14-generic, both under Ubuntu 9.10. Hardware is the new Asus 1005PE netbook, but this Atheros chipset is not new. Have successfully built the latest ath5k from the "bleeding edge" source and modprobe is ok. So the module is loaded but completely fails to see the hardware (same after reboot). There are no blacklisting issues. ifconfig/iwconfig etc. fail to find any devices. I believe this may be due to a new hardware location or vendor code. Here is the lspci output: 02:00.0 Network controller: Atheros Communications Inc. Device 002c (rev 01) I have not seen 002c mentioned in relation to this chipset before (usually 168c I think). I have got the adapter working via ndiswrapper and a Windows XP driver. Without this, there doesn't seem to be any messages relating to the wireless adapter in dmesg or `lshw`.
So, the 168c is the vendor id, 002c is the device id. You should see both if you do lspci -vnn. It seems to fall in the range of IDs assigned to ath9k though. What happens if you add the appropriate stanza to ath_pci_id_table[] in drivers/net/wireless/ath/ath9k/pci.c ?
Thanks for the tip Bob. As you suggested, I added the device id to ath_pci_id_table in ath9k/pci.c and recompiled. This time we do at least see that the hardware is probed (dmesg output): [ 101.419504] ath9k 0000:02:00.0: enabling device (0000 -> 0002) [ 101.419527] ath9k 0000:02:00.0: PCI INT A -> GSI 17 (level, low) -> IRQ 17 [ 101.419553] ath9k 0000:02:00.0: setting latency timer to 64 [ 101.419690] ath9k 0000:02:00.0: Failed to initialize device [ 101.419728] ath9k 0000:02:00.0: PCI INT A disabled [ 101.419750] ath9k: probe of 0000:02:00.0 failed with error -95 I thought that I should try a similar approach for the ath5k and so found the table ath5k_pci_id_table in ath5k/base.c. Again the hardware was probed, but unsuccessfully: [ 109.720483] ath5k 0000:02:00.0: enabling device (0000 -> 0002) [ 109.720505] ath5k 0000:02:00.0: PCI INT A -> GSI 17 (level, low) -> IRQ 17 [ 109.720530] ath5k 0000:02:00.0: setting latency timer to 64 [ 109.720612] ath5k 0000:02:00.0: registered as 'phy0' [ 109.722732] ath5k phy0: POST Failed !!!
