Hello.

Wow, it`s really take long time. :-)
I`m sorry but I now on other job and don`t have this servers and such 
task. So I can`t reproduce it.

AFAIR on 2.6.35.6 I have problems with Dell raid drivers so I can`t test 
it and on 2.6.36-rc5 my test with iozone was completed successfully. So 
I think it was a kernel problem(other env not changed), may be drivers.

But again - sorry, I can`t test it any more.
But if you find\confirm\fix this problem I will be glad if you can 
inform me. May be I will use this setup in future.
