I have a USB ethernet dongle. It works with kernel-2.6.33.6-147.2.4.fc13.x86_64. But it doesn't work with kernel-2.6.34.4-41.fc13.x86_64. DHCP client can't get IP address.
What kind of dongle is it? (usb vendor and device ID, plus whatever brand name and model it says on the packaging) What kernel messages do you get when connecting it on 2.6.33? Are they the same on 2.6.34?

Can you capture traces of the DHCP requests with wireshark or tshark?

Possibly fixed in 2.6.34.6-52
(In reply to comment #6) > Possibly fixed in 2.6.34.6-52 It doesn't make a difference.
Fixed in 2.6.34.7-56.
