[Haifux] [SOLVED] Slow system response under heavy disk load

Some of you have heard me complaining about bad system response when 
making massive writes to the disk. I thought it was the software RAID, 
or maybe the disk encryption, but it turns out it was a kernel bug. If 
you have a fairly recent kernel (released during the last year or so) 
but not a fresh 2.6.36, odds are that you have that problem too.

I've documented my findings (and how to see if you have that problem too) at
