 Can you please show the part of dmesg that talks about bce0 ?

 Thanks,

 Martin

 dmesg | grep bce
 bce at pci5 dev 1 function 0: Broadcom BCM4401-80 10/100 Ethernet
 bce0 interrupt at ioapic0 pin 21
 bmtphy0 at bce0 phy 1: BCM4401 10/100 media interface, rev. 0
 bce0: Ethernet address 00:16:d4:b4:ad:cf

 I've ordered some usb ethernet interfaces, so I can put this machine
 online and download debugging tools, I should have it in a few days

 Can you try booting with -c and then "disable bmtphy"?

 Hi Martin,

 I tried disabling bmtphy, but didn't work.

 I got the usb ethernet adapter today, now I can download any debugging
 tools I need to solve this

 So you got ukphy0 instead and carrier status still did not change?
 Sounds like your chip needs some special quirks. Any bce experts?
