Correction... it isn't 2.6.18 that fixes the problem. It is compiling
without LOCKDEP or PROVE_LOCKING. I remove those and suddenly a
3 drive raid5 is faster than a single drive rather than much slower.
Bill: Do you have LOCKDEP or PROVE_LOCKING enabled in your .config ??
I have to check tomorrow, I'm using the Fedora kernel (as noted in the
first post on this) rather than one I built, just so others could verify
my results as several have been kind enough to do. Have to run, but I
will check tomorrow or Monday morning early at the latest.
