As far as I can tell it seems to point to the reading of the phy registers. In the driver code at the beginning of the xe_mii_init() routine it does a xe_phy_readreg() of a phy status register which is supposed to return a particular response but it returns all ones. In fact any read of the phy registers return all ones. It seems that something in the chip may not be initializing correctly and therefore the phy is not responding? As soon as the right response is returned from the phy register everything works after that. I've tried adding delays and removing delays but have not had any luck. What happens on my Sony VAIO F560 and Xircom CE3B pccard is the pccard is detected and starts to initialize and autonegotiate but it doesn't detect the phy and therefore it timesout and tries again. Sometimes it takes 6 or 7 retries other times it takes only 1 or 2 retries. Sometimes it(the phy) never gets detected. I have been looking at examples from other codes and tried some modifications but no luck yet. I wonder if it has to do with other source code like the pccardd or ISA code? Maybe the IO ports are not getting mapped correctly? Randal To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-mobile" in the body of the message
