Description Michael Moll freebsd_committer freebsd_triage 2011-05-08 23:10:06 UTC
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: <VIA Networking Velocity Gigabit Ethernet> port 0xcc00-0xccff mem 0xdfdff000-0xdfdff0ff irq 28 at device 0.0 on pci3
vge0: attempting to allocate 1 MSI vectors (1 supported)

ip1000phy0: OUI 0x0009c3, model 0x0019, rev. 0

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

Log:
  Fix a bug in r221407; this driver doesn't add the media itself.
