It is good, however, that you pushed the patch upstream. John W.

I disagree with part of Michael's comments. I think we should have a dprintk, rather than dprintkl, so that we get printouts from all four of the sprom values. That way the user will be able to report the numbers we need. As this would not limit the log entries and potentially generate thousands, there should be a variable like bcm43xx_max_led_err to limit the number of log entries. I will propose a new patch once I get the data for the second case. In the meantime, the patch you have pushed upstream will fix the BCM4303 led assertions. Larry
