Hi,
in mmotm-2009-07-30-05-01, the patch named
memory-controller-soft-limit-organize-cgroups-v9.patch
causes qemu fail to boot with tons of:
BUG: scheduling while atomic: async/2/480/0x10000002

Looks like an omitted unlock. I don't see anything suspicious in the
patch though.
The W taint flag is from:
