The problem is that the "solution" varies. On some systems, ignoring the probe failures does not result in working ports. We do not understand the mechanism of the failure, so it's not possible to work around it. Bruce Evans (bde@freebsd.org) is the person to talk to about this.

The EEPROM is read/written by the firmware, not the chip. It is possible that they are using a new checksum algorithmm, or that the firmware is buggy. You may wish to investigate the algorithm and results to verify this. -- \\ Sometimes you're ahead, \\ Mike Smith \\ sometimes you're behind. \\ mike@smith.net.au \\ The race is long, and in the \\ msmith@freebsd.org \\ end it's only with yourself. \\ msmith@cdrom.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hardware" in the body of the message
