via-velocity Oops when unloading module

[Kazutoshi Morioka]

Hello,

I installed Fedora Core 3 test 1 and upgraded with yum to Fedora development repos.
New VIA verocity driver in development kernel 2.6.7-1.xxx (including 2.6.7-1.501) works,
but every time I stop/restart network, Oops occur in that driver.

The card I'm using is GbE-PCI (http://kuroutoshikou.com/).
It seems a generic PCI NIC (OEM from taiwan?).
