kernel BUG at slab.c:1238!

That's a really strange oops to see. It's testing that the GFP flags
match the slab's flags. To get an oops there, you'd have to have a
non-dma slab (which makes sense), but you've called the kmem_cache_alloc
routine with a DMA flag. Line 444 of kernel/signal.c clearly doesn't do
that! Could the args be being corrupted while being passed?

I had sometimes hangs while calibrating delay loop with earlier kernels,
Alan Cox suggested SMI screwing things up. This bug is earlier and new.

What does a backtrace look like?

Too bad, kdb not fully init, modules not loaded, so no BT command.
