Comment 135 for bug 620074

Could this be the same bug as: http://lkml.org/lkml/2008/6/15/163 ?

Because on the same system on which I have the same sympthones on what
his bug describes, also the following happens:
http://beheer.eduwijs.nl/kernellog-brikama.log

I need to say that changing the IO scheduler from CFQ to AS seems to
help a bit. It will not solve the problem, but the system will be much
more responsive.
