I've tested this a little further. The behavior is independent of the
kernel version used (tested back to 2.6.37). My SSD is also fine and a
freshly created xfs partition shows no problems, too.
Please note that the affected partition is used very heavily here
(several git trees, daily backups of / and the Gentoo build-dir reside
there).
So it appears that the observed "hangs" are the result of a strongly
aged file-system.
