Tried to boot using SLUB under lguest with 2.6.21-mm2. Got the
following:

...

And no sign of further progress. SLAB worked fine.

Add slub_debug to the command line. Any changes or any additional 
diagnostic output?

Exact same thing happens on real hardware here.

Anyone could try this with slub_debug on the kernel command line? Another 
assumption that page size allocs are page size aligned?
