Hey guys - our system test team opened a defect on this, since Ubuntu (as it stands) is broken now with CAPI Flash cards.
Dion opened bug https://bugzilla.linux.ibm.com/show_bug.cgi?id=140054 .
So - this is important. You need to tested to confirm that this is in-fact the root cause of Dion's

Did we just make that up? It seems like a lot, but then
