system started to hang under heavy IO load. Using SATA disk, USB-SATA
converter, even USB flash, i've made some tests with it.

Sympthoms - starting to rsync centos archive - http://mirror.yandex.ru/centos/
to local repository and/or starting periodic daily system hangs soon.
Disk activity according to systat -vm goes to zero, system not halting, but
stucks forever on any disk io, still can input to virtual consoles, try to
login(actually - hangs also), no network or ping, zero on messages/failures
from kernel on console0.

My custom kernel config:
