| Btw, can you send me your .config so that I can try to reproduce?

Attached, but as Linus suggested, I turned off the AMD microcode driver,
so it should be the same if you turn it back on. If you want, I can
do it and re-send so you have a more pristine .config. Let me know.
 
| I'm assuming you're booting latest Linus' tree on it?

Yes.

Without the AMD microcode driver, the kernel boots just fine (I knew
it wasn't GFS2 because my root partition is ext4).

I'm doing some basic smoke tests on GFS2, but it seems to be running
just fine with Linus's aforementioned patch. I'll see if I can push it
a little harder.
