Hi,

installed A07 (previous version is A05)

now my LAN card doesn't work.

$ dmesg | grep wm0
wm0 at pci0 dev 25 function 0: PCH2 LAN (82579LM) Controller, rev. 4
wm0: interrupting at ioapic0 pin 20
wm0: PCI-Express bus
wm0: No EEPROM
wm0: unable to read Ethernet address
wm0: unable to read Ethernet address

Some ideas? :-)
