Description H.J. Lu 2010-08-19 15:03:25 UTC 
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.
Comment 1 Chuck Ebbert 2010-08-21 07:54:00 UTC 
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?

Comment 3 Chuck Ebbert 2010-09-01 23:19:23 UTC 
Can you capture traces of the DHCP requests with wireshark or tshark?
