3ware: no cards found in 2.2.19, cards found in 2.4.x
I have a quad xeon 2GB system running Oracle which I am reverting to 2.2.x because of 2.4.x's less than desirable VM performance (causing a 2x Oracle slowdown, reported about a month ago on linux-kernel). I foolishly put a 3ware card in at the same time as I "upgraded" the box to 2.4.4, so now I am in the undesirable position of needing to go back to 2.2.19, but that kernel cannot find the card. I get the following message during boot:
3w-xxxx: tw_find_cards(): No cards found /lib/moduless/2.2.19-2GB-SMP/scsi/3w-xxxx.o: init_module: Device or resource busy
I have tried compiling the 3ware driver version 1.02.00.{004,006,007} all with the same result. Has anyone managed to use a Suse 2.2.19 kernel with 3ware cards with any success? The 1.02.00.004 driver is from the stock 2.2.19 kernel, the .006 driver is from 3ware's website, and the .007 driver is from 2.2.20pre9.
Any hints appreciated,

I first suggest that you try kernel 2.4.9 or the latest of 2.4.8-acN.

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 :) .

Both of these address the VM issues. I won't say VM is perfect, but you can't know if it works better for you like it does for me until you try it. Upgrading a kernel is a pretty quick and painless job. As to the corruption, I don't see enough below to make a start as to the cause.
