Just got my empeg-car, loaded ~1Gb via ethernet but sync failed at about 75%.

Hope you managed to upgrade to 1.01. If you are still having problems with ethernet after that, please try this modified kernel:

http://bkernel.sourceforge.net/tmp/zImage.eth-patch

It includes a patch to the ethernet driver that solved a timing issue for me (see my post about it). The BBS FAQ has an entry on how to upgrade the kernel.

Good luck,
Borislav
