2.6.19.2 nfs BUG: warning at mm/truncate.c:398/invalidate_inode_pages2_range()

[Frank van Maarseveen <frankvm@frankvm.com>]

FYI,

Just captured this one, I'm not sure it's NFS at fault because I saw
at least another AIO related mm/truncate.c:398 report with a totally
different stack trace.

The machine seems still running happily, as usual with a considerable
load. kernel is tainted by fglrx.
