OK, I started looking through the errata sheet. Let me stress I don't
normally read these things, so...
But the first thing I notice is that I tried to figure out what stepping
I have (in the Identification section), it says should look for vendor
ID 8086h and device ID 3403 or 3406. I have neither. I have 3405.
Which, appears to make sense, because this is not a Intel 5500/5520
chipset, its an Intel X58 chipset. That seems to have a different
specification update, despite being from the same family:
http://www.intel.com/content/dam/doc/specification-update/x58-express-specification-update.pdf
00:00.0 Host bridge [0600]: Intel Corporation 5520/5500/X58 I/O Hub to ESI Port
[8086:3405] (rev 13)
so I have a X58, Stepping B3. Appears to be issue 69 instead, and is
supposed to happen on B3. Added back in July '09. Odd that Asus hasn't
yet heard... Especially since they didn't release the board until 2010.
[Still trying to make my way through those documents.]
PS: The linked bug report
https://bugzilla.redhat.com/show_bug.cgi?id=887006 is apparently secret :-(
