I don't know if this is of any interest. I upgraded from ubuntu gutsy gibbon to hardy heron and this problem occurred. Booting with the previous kernel (2.6.22) and forcedeth driver 0.60 everything works. In 0.61, the MAC-address is in fact read backwards. This is the upgraded entry in the 70-persistent-net.rules;
# Converted from /etc/iftab on upgrade SUBSYSTEM=="net", DRIVERS=="?*", ATTRS{address}=="00:13:8f:e9:da:e5", ATTRS{type}=="1", NAME="eth0" I solved it by replacing it with; # PCI device 0x10de:0x03ef (forcedeth) SUBSYSTEM=="net", DRIVERS=="?*", ID=="0000:00:07.0", NAME="eth0" and to get the correct MAC-address instead of the random one; /etc/network/interfaces iface eth0 inet dhcp hwaddress ether 00:13:8f:e9:da:e5 Output from lspci; 00:07.0 Bridge: nVidia Corporation MCP61 Ethernet (rev a2) Subsystem: ASRock Incorporation 939NF6G-VSTA Board Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- Status: Cap+ 66MHz+ UDF- FastB2B+ ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR- <PERR- Latency: 0 (250ns min, 5000ns max) Interrupt: pin A routed to IRQ 21 Region 0: Memory at dfffd000 (32-bit, non-prefetchable) [size=4K] Region 1: I/O ports at e480 [size=8] Capabilities: [44] Power Management version 2 Flags: PMEClk- DSI- D1+ D2+ AuxCurrent=0mA PME(D0+,D1+,D2+,D3hot+,D3cold+) Status: D0 PME-Enable+ DSel=0 DScale=0 PME- Capabilities: [50] Message Signalled Interrupts: Mask+ 64bit+ Queue=0/3 Enable- Address: 0000000000000000 Data: 0000 Masking: 00000000 Pending: 00000000 Capabilities: [6c] HyperTransport: MSI Mapping -- Ethernet device's number increases by one after every reboot https://bugs.launchpad.net/bugs/153727 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
