​Michael,​

​'test0' does NOT boot -- same symptoms as stock system. (stacktrace thrown
about 30 seconds from boot)

i rebooted into PXE FAI startup, /target-mounted the system's disks, and
redid the 'dpkg -i' for the 'test1' debs.​

I've rebooted successfully into 'test1' eight times now.  FWIW, the LSI SAS
6/iR responds at about 32 seconds into the boot (just past the
arbitrary/too-short 30 second default imposed upstream)
