When booting a FreeBSD 7.1 RELEASE CD (bootonly, disc1 or livefs) the kernel
hangs after probing the Attansic Gigabit onboard NIC on my ASUS M2V mainboard.

The following lines will displayed before the system freezes.

age0: <Attansic Technology Corp, L1 Gigabit Ethernet> mem 0xfbbc0000-0xfbbfffff
irq 36 at device 0.0 on pci4
age0: PCI device revision : 0x00b0
age0: Chip id/revision : 0x9006
age0: 1280 Tx FIFO, 2364 Rx FIFO
age0: MSIX count : 0
age0: MSI count : 1
age0: Using 1 MSI messages.
age0: Read request size : 512 bytes
age0: TLP payload size : 128 bytes

Use an ASUS M2V mainboard (with GBit enabled) and boot a FreeBSD 7.1 
RELEASE installation CD. The problem also occur with the current 
"stable" (7.2-PRERELEASE #2). When the kernel is build without the 
age driver, the system will freeze when the age module is loaded
with kldload.

Deactivate the onboard GBit interface via the BIOS (not really a fix).
