>Description:
Below the relevant dmesg output at kernel load time. The 3.1 kernel doesn't exhibit this problem on the identical hardware configuration.

>How-To-Repeat:
I've no idea if the problem is peculiar to my Micron Millenia PII (300Mhz) machine or whether other systems with 3c509b cards do exhibit this problem as well.
