This means that sometimes one of the on-board arge interfaces (which is linked to the stand-alone PHY) can't find a PHY and it simply fails to attach. >How-To-Repeat: Just keep rebooting an atheros MIPS board with an onboard AR8x16 switch. >Fix: Luis Otavio D'Souza found that disabling the page cache feature fixes it. Ie, always set the page id before read/writing the switch register. >Release-Note: >Audit-Trail: >Unformatted: _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-bugs To unsubscribe, send any mail to "[email protected]"
