o.k. finally finished with the bisect: reverting this gets things going on 2.6.33-rc5 789d03f584484af85dbdc64935270c8e45f36ef7 is the first bad commit commit 789d03f584484af85dbdc64935270c8e45f36ef7 Author: Jan Beulich <JBeulich@xxxxxxxxxx> Date: Tue Jun 30 11:52:23 2009 +0100 x86: Fix fixmap ordering The merge of the 32- and 64-bit fixmap headers made a latent bug on x86-64 a real one: with the right config settings it is possible for FIX_OHCI1394_BASE to overlap the FIX_BTMAP_* range.

(as for the x86_32 working and x86_64 failing not sure); I'm curious to see if anybody else is hitting this? Justin P.
