Hey all, I'm just letting you know that I have been having issues getting the the AHB support with the ath5k driver working (from compat-wireless 2011-01-05). I'm testing it on an ubiquiti bullet 2 device which internally is a AR2315 WiSoC. I am using openwrt backfire with the mac80211 package patched to use a later version of compat-wireless (ie one with AHB support in ath5k). I had to modify some of the patches in openwrt so they applied cleanly, but don't think any affected the ath5k (and would cause the problem i have). Basically the issue is this. When I try to load the module as is in the source tree, the system hangs and module never loads (device restarts itself). I tried a bit of debugging (sorry about any newbie techniques here, im new to kernel debugging) by just printing and returning errors after every main function called. The problem seemed to be with the first time it called ath5k_hw_reg_write, which from my tracing seemed to be in th wisoc reset function in the following chain. ath5k_hw_reg_write (ath5k.h) ath5k_hw_wisoc_reset (reset.c) ath5k_hw_nic_wakeup (reset.c) ath5k_hw_init (attach.c) ath5k_init_softc (base.c) ath_ahb_probe (ahb.c) I then tried out a few things in the vain attempt to get it to load the module, one which seemed to work is taking out the ioremap_nocache call in ath_ahb_probe, and set mem to be res->start (on my system this is 0xb0000000 (the same as what madwifi tells me as well)). With this /fix/ the module now loads, gives the output below, but i can't bring the interface up (device crashes again). Atheros AR2315 chip found (MAC: 0x87, PHY: 0x48) continuing traces when bring interface up brings me to another ath5k_hw_reg_write call in the following chain ath5k_hw_reg_write (ath5k.h) ath5k_hw_start_rx_dma (dma.c) ath5k_rx_start (base.c) ath5k_reset (base.c) ath5k_init_hw (base.c) ath5k_start (mac80211-ops.c) I am sorry about the long email, but I thought the more info you guys have, the better. If you have any ideas I can try, any more testing you may need me to do, or anything that could help me get it working, let me know, and i'll do my best to get anything done asap.
