OK, I'm trying this with the latest (git) fio. This command line:

% sudo fio --name=replay --read_iolog=kerncomp.bin --filename=/dev/sdc

Produces only this output:

replay: (g=0): rw=read, bs=4K-4K/4K-4K, ioengine=sync, iodepth=1
Starting 1 process
Jobs: 1 (f=1): [W] [0.0% done] [ 0/ 0 kb/s] [eta 19h:59m:23s]

It actually shows a few thousand kb/s for the first few seconds, but
then it drops to 0 and the eta just keeps going up.

Using Debian testing on IA64, vanilla 2.6.22.3 kernel.
