Just tried my "tar cp . | mbuffer | bzip2smp >/usb3/ext4/foo.tar.bz2 
using a kernel 3.6 without using fglrx and without any additional 
patches. The first try already ended up in a broken archive (tar djf => 
bzip2: Data integrity error when decompressing), but (again) without the 
BUG() in fs/buffer.c getting hit. Will do some more tests, trying hit 
that BUG().

Alexander
