I think I have a similar problem, I believe starting around 2.1.8x.
If there's heavy disk activity, whatever process is involved gets
stuck, and I can't kill it. Unlike Carsten, though, it is repeatable
-- if I do a 'cp -a /usr /mnt' where a different drive partition is
mounted in /mnt, cp will hang.
ps -axlw shows cp as such:
100 0 190 181 0 0 2632 1844 wait_on_pa D p0 0:26 cp -a /usr /mnt
My /var/log/messages file also has the following messages:
