I know some of you will be upset because of the revival of an old post... but it's still an ongoing issue, and we might be able to get a resolution to it now.
I'm going to post an IRC log so that you may see the issues and our attempt at fixing it (also I don't have to re-type it this way):
<Newb4Life> Well... Im going to the fedora forums for this one but I might as well run it by here as well:
<Newb4Life> When I load Fedora (2.6.30.10-105.fc11.i686.PAE) I get an error that I do not get when I run 2.6.30.9-102.fc11.i686.PAE
<Newb4Life> That error is (and actually... its not even an error): e100: eth0 NIC Link is up 100 Mbps Full Duplex
<Newb4Life> and then it just sits there.
<***> hold on a second, Newb4Life
<Newb4Life> oh wait.. one more line after that... THEN it just sits there: ADDRCONF(NETDEV_CHANGE): Eth0: link becomes ready
<Newb4Life> Thanks ***
* ***** (~*****@***.*******.******.**.*****) has joined #bleepingcomputer
* w00t gives voice to *****
<*****> So it sits there on boot?
<Newb4Life> yep
<*****> what you pasted means the ethernet card is up, the error is after that
<*****> so you don't actually see the error
<*****> is this while upgrading?
<Newb4Life> yep. Imediately after
<Newb4Life> I can only run the old version.
<*****> try rebooting to the bios and disabling the onboard nic
<*****> if there is one
<Newb4Life> Tried that the first time this happened to me. XD I ended up reinstalling the OS. BUT I will try again seeing as there were a few errors last time.
<Newb4Life> brb
-------------------------------
<*****> nothing?
<Newb4Life> literaly
<*****> hm
<*****> i found a posting on the fedora forums
<*****>
http://fedoraforum.org/forum/showthread.php?t=26902 there may be some help in there
<Newb4Life> Thanks *****

reading up
<*****> np i need to run to the store with the kid so ill be back later
<Newb4Life> kk. From what I have read there isn't a known fix for this yet other than running an old Kernel. It is apparently a problem with the network subsystem.
<Newb4Life> but sheesh... I just noticed the dates on that post.
<Newb4Life> One user claimed they solved it with acpi=off but I am not entirely sure how to go about doing this.
<Newb4Life> Im guessing its the Kernel selection menu?
<Newb4Life> hit e, select your kernel, and hit e again?
<Newb4Life> well.. Im going to eat while I wait for your return. I will still be here just un-able to type.
And then I ate... and now I am posting here.
Thanks for the help guys! Sorry for the log but I figured it would make it easier!
