According to Red Hat, the DL140 G2 is certified, but not the G3.  See:

http://bugzilla.redhat.com/hwcert/list.cgi?product=Red+Hat+Hardware
+Certification&quicksearch=DL140

You'd have to check bugzilla for that.

You didn't say what kind of panic you're seeing and that'd be quite
helpful.  Some things you might try would be adding any one or more of
the following options to the "boot:" command line:

	noapic
	nodma
	noprobe

e.g. "boot: linux noapic nodma"

And you might also want to try doing a text-mode install:

	boot: linux text

and append whatever options you feel are useful.  For a full list of
options, see:
