The truth is hidden in the changes between 2.6.10-bk11 and -bk12.


Everything up to 2.6.9-rc2-bk1 worked ok, -rc2-bk2 was broken due to the vsid changes.
This change fixed it, up to 2.6.9-rc2-bk9
Then proc_claim started to return 0xdeadbeef in -bk10.
Workaround is to turn this value into PROM_ERROR. This helps up to 2.6.10-bk11,
-bk12 is stuck after kicking other cpus.
