Association repeatedly fails with some "direct probe to x timed out" messages (see syslog excerpt below), although it will generally associate eventually, after many tries. Bisection identifies 8aec7af (ath5k: Support synth-only channel change for AR2413/AR5413) as offending commit. Prior to this commit there are no direct probe messages at all in the logs. I've also found that forcing fast to false at the top of ath5k_hw_reset() fixes the issue. I'm not sure what the connection is between this commit and the timeouts. Any suggestions?
