First both worked fine (4.2R) and somewhen when I was following -stable it broke the same way Forrest sees it: The 100Mbit LED lights up when I connect the cable (stays on when I remove it, but that's the same with standard fxp cards). Although there is some activity on the LAN (but definatly no SYN attack as someone mentioned) the activity LED on this board does not light up (it does on standard fxp cards). Now both my embedded boards are network wise dead because the fxp chip is appearently in some sort of sleep mode. I tried running Winblows on the board to see if the Intel Windows driver could get the chip back alive but nope. The same symtoms, 100 LED on, no activity. But always I'm able to ping myself with the interface IP. Ifconfig always says "no carrier". Setting it to whatever manually doesnt help at all. Stays the same. The same behaviour with Winblows, can ping itself but nothing outside. My embed boards were working perfectly fine with -stable until approx. two month ago when it happend to both after a cvsup and make world. Might it be related to the power safe changes that went into fxp? After giving it a last try with a fresh install of 4.2R which again showed the same symtoms I was on the way so send the embeds back to my supplier and tell him he's selling junk... luckily I stumbled across this thread. > The other thing is that you're running 100mb/s; the previous > lockups I've seen with this board were for 10mb/s.

Will hook up a serial console. -- Andre To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
