[Bug 1250828] Re: freeze on diskIO without real IO
apport information
** Tags added: apport-collected saucy
** Description changed:
I have ubuntu 13.04-13.10 with kernel 3.8-3.12 (from distributive and from http://kernel.ubuntu.com/~kernel-ppa/mainline/ )
Sometimes (in 1-3-5-... minutes) then some program use disk i has freeze it program, and if different program use disk in it time - it may freeze too. But htop and iotop show 0 diskIO at this time. Cpu-usage ~1-5%.
