Hi
I'm new to this list, so please bear with me.
I have a Dell Latitude E6400 running Ubuntu Natty amd64 (kernel
2.6.38-12-generic) which I have problems with my e1000e nic. Very often
my nic does not work. I.e. ifconfig lists eth0, but ethtool is not able
to access the device (see below). If I do an ifup, the operation simply
hangs.
It seems like, even though unproved, that to get my nic working, I need
to boot Win7 and use the wired network. If Win7 is used with the cable
inserted, it seems Linux is able to use the nic afterwards. If Win7 is
used without wired ethernet, the e1000e driver misbehaves in Linux. To
me this suggests that its some Dell specific setting which Linux does
not know of. I've checked the BIOS settings, but nothing there which
suggests such a setting.
Is this at all familiar to anyone?
PS! My Dell's motherboard is brand new. I had a thermal meltdown, so
Dell has recently replaced the entire board.
Best regards,
Svein Seldal
