I get the same messages, but everything works fine. I've been getting them for a few years now, always after a reboot: xl0: transmission error: 90 xl0: tx underrun, increasing tx start threshold to 120 bytes xl0: transmission error: 90 xl0: tx underrun, increasing tx start threshold to 180 bytes xl0: transmission error: 90 xl0: tx underrun, increasing tx start threshold to 240 bytes xl0: transmission error: 90 xl0: tx underrun, increasing tx start threshold to 300 bytes xl0: transmission error: 90 xl0: tx underrun, increasing tx start threshold to 360 bytes (not exactly all at the same time of course). Machine functions just fine as far as I can tell. --Stijn --=20 Coughlin's law: never tell tales about a woman no matter how far away she is, she'll always hear you. -- Cocktail --zhXaljGHf11kAtnf Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.0 (FreeBSD) iD8DBQFCX7elY3r/tLQmfWcRAgU+AJ43n3NDpQycb8xkO/Vtyc5jF5Jm+wCgsJ+2 DyvZgp/kRr/M1qUa8XWCO0w= =pLQ1 -----END PGP SIGNATURE----- --zhXaljGHf11kAtnf--
