This entry is being used for tracking a regression from 2.6.36. Please don't
close it until the problem is fixed in the mainline.

I changed it to the 2.6.35 regression list.

Also present in 2.6.32 (Should have finished reading that thread). 
Note that earlier kernels were not tested, so it's not clear that it is a regression at all... 

Did this got resolved in the meantime?

No, not resolved. I diagnosed it to being related to a distro sudo configuration change causing the problem:

and as far as I'm aware nothing has happened from there.
