Subject: Heads up: Infiniband kmem race during startup

The integration of

6554564 slab allocator cannot release slabs with lonely buffers

in snv_91 introduces a race condition in systems with Infiniband
hardware. If you install snv_91 on a system with Infiniband hardware,
you are likely to hit

6709564 Panic in ibmf_send_wqe_cache_constructor() due to kmem race.

Sorry for the inconvenience. A fix is planned for snv_92.
