Using Intrepid Alpha 5, with kernel 2.6.27-2-generic, the new atheros driver ath5k frequently fails to initialize the hardware at boot time or during resume. I have an AR5424 in a ThinkPad X61. When the device fails, I get messages like these:

Sometimes it goes on and on like that, complaining about every frequency the hardware is capable of using. In any case, it never works right after that. It is necessary to power down the machine. The madwifi driver in Hardy didn't have this problem.
