Crash at boot on 2.6.29-rc5

I'm trying to boot Fedora Rawhide (Fedora's kernel contains daily merges
with Linus) on the XO, and it's crashing at boot if I have the libertas
firmware installed.  Here's a dmesg:

To summarize the dmesg:  we get a jffs2 lockdep warning, then
networking comes up, then NetworkManager starts, and as it starts
we see slab corruption with lbs_set_encode() in the backtrace,
and then the slab poison kicks in.  On other boots I've seen things
like spinlock deadlocks inside NetworkManager, and "fatal exception
inside interrupt", so the symptom isn't always identical, but boot
always fails with libertas present.

It looks like jffs2 might be involved, but it isn't -- with libertas
loaded we fail to boot 100% of the time, and without it we boot
successfully 100% of the time.  Any ideas?


- Chris.
