Kernel 2.6.36-2.el5.elrepo on an i686

When I try to ifconfig either of the BCM5906M ports the system panics.

Ideas, fixes ?

[root@Z1010 ~]# modprobe tg3
[root@Z1010 ~]# ifconfig eth2 2.2.2.2/24

Additonal info I compiled the latest kernel 2.6.37-rc8+ and still have the problem.
Also boot with noapic I see this in the dmesg log and interrupts are increasing like crazy:
