PCI card is Atheros AR5413 168c:001b (rev 01). Your kernel is tainted due to the ixp400 module. I doubt it matters in this case, but you should generally try to provide oopses on untainted kernels or else people may just ignore it. > [42949474.280000] Bad mode in data abort handler detected > [42949474.280000] Internal error: Oops - bad mode: 0 [#1] I don't know arm architecture enough to know quite what that means... > [42949474.280000] Backtrace: > [42949474.280000] [<bf2d5eb4>] (ath5k_hw_register_timeout+0x0/0xcc [ath5k]) from [<bf2d645c>] (ath5k_hw_nic_reset+0x17c/0x2bc [ath5k]) > [42949474.280000] [<bf2d62e0>] (ath5k_hw_nic_reset+0x0/0x2bc [ath5k]) from [<bf2d6778>] (ath5k_hw_nic_wakeup+0x1dc/0x570 [ath5k]) I think it's an endianness issue -- ath5k probably hasn't seen much testing on BE platforms. ath5k_hw_register_timeout polls a register in a loop waiting for a specific bit to be set or cleared (this happens e.g. while calibrating the card). The problem is ioread32 will return an le32 but as far as I can tell we just assume it is native endianness. I don't have an appropriate platform available, would you be willing to test patches? -- Bob Copeland %% www.bobcopeland.com -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
