Hardware is Asus EEEPC 1015PE.

>Description:
	o interface alc0 (full dmesg etc see below) works fine,
	  if the ethernet cable is plugged in during boot.
	o if the cable is not plugged in, no combination
	  of "ifconfig alc0 down, up, <ip-assigment>, etc.
	  brings it back to work.

For full details (verbose dmesg, pciconf, ifconfig -a, dmidecode) see:

>How-To-Repeat:
	a) boot with cable plugged in, everything works -- unplug/replug,
 	   it still works.
        b) boot without cable plugged in, it can not be made to work.
>Fix:

	No fix available.
