I'm using F18-beta-rc3 on a Dreamplug and experiencing kernel soft
lockups when I do a git clone. I first noticed this happening with
the 3.6.3-3.f18.armv5tel.kirkwood kernel (it may occur on earlier
versions too), but it is still occurring with
3.6.10-6.fc18.armv5tel.kirkwood.
I get the following output on the console:

And the above keeps repeating until I power off the plug.
Is this of interest on this list, or should I report it elsewhere?
Please file an issue in Bugzilla:
https://bugzilla.redhat.com/
This will help make sure it does not get lost in the holiday
shuffle. Also, be sure to select 'arm' for the hardware so the
appropriate people will see it.
We used the kirkwood kickstart file you made as the base for the
beta tc3 image. Thank you again for all your hard work on putting
that together. Your efforts made the *plug image possible.
