Re: Poor cardbus performance on TP600 with 6.0-BETA5

Hello Joerg,

on my Thinkpad 600 I have the same troubles when using an IBM Etherjet
10/100-Cardbus-Card (xl-driver). The problems began with FreeBSD 5.3.
FreeBSD 5.2.1 worked fine. I switched back to FBSD 4.11 and now I use my
old D-Link PCMCIA-Card and everything works fine.

Sorry that I cannot help you

Regards

Jürgen
