Re: 3ware: no cards found in 2.2.19, cards found in 2.4.x

[Brian Strand <bstrand@switchmanagement.com>]

Do either of these kernels fix the "2.4.x VM suckage" problems?  I don't 
want to use a 2.4.x kernel because Oracle runs almost 2x slower (with 
identical hardware config) on 2.4.4 and 2.4.6 versus 2.2.16 (and I have 
4G of swap for 2G of physical mem, so that is not the problem), not to 
mention that one of these 2.4.x kernels caused Oracle corruption.  I 
don't feel so comfortable testing new kernels with several hundred GBs 
of customer data anymore :) .
