           Summary: iotop shows too high values
    Classification: openSUSE
           Product: openSUSE 11.3
           Version: Factory
          Platform: x86-64
        OS/Version: openSUSE 11.3

In OpenSuSE 11.3 (Factory, first noticed in M7), iotop shows too high values
(TB/s and more) in columns "disk read" and "disk write". For example, while 'dd
if=/dev/sda of=/dev/null' reports 75 MB/s, iotop shows approximately 200-300
PB/s.

It doesn't seem to be a problem of iotop itself, however, as binary from
OpenSuSE 11.2, run under 11.3 and chrooted to root directory of 11.2
installation, behaves the same (under 11.2 it's OK).

Reproducible: Always

Steps to Reproduce:
1. run iotop
2. run 'dd if=/dev/sda of=/dev/zero bs=1M count=1K'
3. see the output of iotop
4. compare with speed reported by dd
Actual Results:  
Values reported by iotop are much higher (at least 1E9 times) than values
reported by dd.

Expected Results:  
Values should be moreless the same.
