I get these "unable to reset channel" and "noise floor calibration" messages too (ath5k only - ath_pci blacklisted). They are appearing frequently in a few minutes and decrease my tranmission rates because the transmission alway hangs shortly. On the other hand suspend and resume works fine while on ath_pci I don't get my wifi connection back after resuming.
