>Description:
When the onboard interface of a VIA VB8001 board is brought up, the following panic happens with r221661:
Fatal trap 12: page fault while in kernel mode

Part of dmesg:

vge0: attempting to allocate 1 MSI vectors (1 supported)

This worked with a kernel built from sources about one week earlier.
