Hello !

I have gotten  "igbe: bad EEPROM checksum" message on my IBM (Lenovo) T61
Tablet.
I've took a look at NetBSD kernel sources (if_wm.c), that recommends to rea=
d
EEPROM twice :)

Comment from if_wm.c:

/*
		 * Read twice again because some PCI-e parts fail the
		 * first check due to the link being in sleep state.
		 */


Maybe helpful :)
