>Description:
On a Dell Inpirion 7500 (PIII- 500Mhz) with an xl0 card (3Com 3c575B Fast Etherlink XL) cardbus : the network doesn't work :

xl0: watchdog timeout.

Intalling first BETA5 with an ISO CD, I had the problem. So, I reinstall from scratch the machine with a FreeBSD 5.4 patch 7 : no problem, all is working fine, network was up and running without any messages. So, update source tree of 5.4 with cvsup with tag RELENG_6. Yesterday, afternoon. it build "world, kernel" all the night. This morning "installkernel". reboot. Figure the problem. "installworld" then reboot. Allways figure the problem. 

The hardware is not responsible since in 5.4 p7 all is working fine on this machine. I must add that I didn't change anything  (BIOS, hardware, etc). 
>How-To-Repeat:
Install FreeBSD 6 BETA5, with an xl0 cardbus card on Dell Inspirion 7500 (see below) : I can give help, to analyze ;-) but since I didn't develop the xl0 driver, nor the new driver API, I think this is best if a Kernel guru can contact me and drive me in analyzing what's wrong ;-)

None.
