Comment 28 for bug 573259

Same problem exists on a friend's brand new PC:

CPU Intel Core i7 860, 4x 2.8GHz
Mainboard: ASUS P7P55D-E, Intel P55 (USB3.0/SATA3)
ATI Radeon HD 5750 1024MB
8GB DDR3-1333 CL9

Before installation of Ubuntu 10.10, ethernet worked fine in Windows 7 Professional 64bit.
After installation of Ubuntu 10.10 64bit release, ethernet interface stopped working.
After reboot to Windows 7 it said: no ethernet cable connected.
Plug out + plug in of network cable did not help, neither disable + enable network card.
Only solution is to power off and pull the power cable, wait a few minutes and pray.

Is someone of the developers working on this issue?
I have no access to the PC, so I cannot provide any further diagnostic info.
