An Odd kernel problem question

Since I'm on the kernel questions...


We had a problem with our production system.

In reference to using/seeing (7.2/2.4.7-10) an adaptec
  3200S (SCSI Raid Card) which uses the i2o module. Initially
  I had to run a special update routine prior to installing
  the OS in order for the system to see the Raid Drive
  correctly), initally, the smp kernal was installed.

Then in trying to get the onboad u320 driver to work, we
  rebooted to linux-up kernal, thinking the smp was causing
  a problem.

Now, the linux-up kernal is the only one that sees the i2o module,
if we try to reboot in the smp, it doesn't seem recognize the
SCSI card properly.

The only thing we did, was reboot to the single cpu kernel, then
reboot back to the smp kernel. Very strange, at least to me.

It would be nice to get the other 3 cpu's online :) But aside from
a full system reload (which I don't want to do), I haven't been
too successfull.

Anyone have any idea of what might have happened, or what I can do
to get the smp kernel to see the SCSI RAID drive again? 

The problem seems to be it's using the i2o_block driver instead of
the dpt_i2o driver, seems the 3200S requires the dpt_i20.

Supposedly 7.3 sees the card properly, but since the mfg of our
software hasn't cleared 7.3 as usuable (ie. we won't support you
if your running 7.3, but 7.2 we will) we can't upgrade yet.

Thanks
