PROBLEM: (CLD MGO103853, CLD MGO103295, CLD MGO103959) (Patch ID: OSF440-005)
********
This patch fixes a kmf for a bucket 2 (64 byte corruptor) problem when the
type of SCSI device dynamically changes.

A typical stack trace:
       panic
       trap
       _XentMM
       malloc(size = 64, bucket 2)
       falloc
       accept1
       oaccept
       syscall
       _Xsyscall
