The same problem was noticed on kernels about 2.5.11-12. poldek
(rpm-updater from PLD distro) is loading its packages base and then
hanging hardly. SAK helps. But then, while trying to eg. ps all processes,
'ps' process also hangs. I'm sending strace of poldek process, end of it
is this 'hang moment'.
