Usually private submission of logs (PGP) is acceptable.

Note, I am not claiming Xen's `dmesg` contains truly concerning
information.  The issue is there is enough data for problematic
information to unintentionally leak in.  Alternatively no pieces would
be individually concerning, but all together information may leak.

Hopefully ACPI table addresses nor table order are effected by the
motherboard serial number, yet those could readily leak information.

So far this is acting like a major bug.  The paucity of reports is likely
due to few people using RAID1 with flash (most people relying greater
reliability even before the first large studies came out).
