 forster (on testing list) reports that 11.2.0 build 23 doesn't boot, it
 can't find the root device.

 He has lots of bad blocks, here are the addresses:
 {{{
 a
 1a
 2a
 3a
 4a
 ... the a's through to fa

 then ok for a while

 the a's  30a thru to 3ba
 the a's  50a thru to 5ca

 first bad block thats not 'a' is at 6b1
 }}}

 I have an XO-1 which can't boot 11.3.0 build 1. It has a bad block
 conveniently placed at address c1, which is either at the end of the boot
 partition or at the start of the root partition. Other bad blocks are at
 1011, 1092, 10cf, 10d1, 10dd, 1138, 1311, 1341, 1c11, 1c92, 1ccf, 1cd1,
 1cdd, 1d38, 1f11, 1f41. The system boots (with a few ECC failures in early
 boot), then gets overthrown with ECC failures by the time it reaches the
 first few init scripts.
