 Not surprisingly, the problem still exists in next-20091229 :-) But actually, I think it might be even as old as 2.6.31-rc3. See

http://lkml.org/lkml/2009/7/14/120

for reference. Different (still older toolchain), but very similar failure.

@Andreas: did you ever had this resolved? I never saw a followup

Cheers
Martin
