Re: 2.6.36 io bring the system to its knees

[dave b]

I now personally have thought that this problem is the kernel not
keeping track of reads vs writers properly  or not providing enough
time to reading processes as writing ones which look like they are
blocking the system....

If you want to do a simple test do an unlimited dd  (or two dd's of a
limited size, say 10gb) and a find /
Tell me how it goes :) ( the system will stall)
(obviously stop the dd after some time :) ).

iirc can reproduce this on plain ext3.
