Managed to make it all the way through populating two mock chroots
simultaneously with transparent hugepage support disabled, pretty sure
that's the answer, so please go ahead with any recent failed builds (I
think all I saw was ffmpeg builds from Nicolas and
xine-lib-extras-freeworld from Rex).
So apparently, the necessary fix is actually a host-side kernel
update, which is in the latest EL6 kernel build (2.6.32-52.el6) and
the latest F13 kernel in updates-testing. Not sure yet about Fedora
12, which is what the host here is running. Will get a patched kernel
on there shortly, one way or another.
(My build croaked with a "g++: Internal error: Killed (program
cc1plus)", which may or may not be ongoing random corruption that a
patched host kernel might fix).
