Description of problem:
Is it possible to add driver for Areca Raid controller to FC4? There is already a patch out there for the 2.6.12 kernel that is verified and certified by vendor. I tried it using it with 2.6.11 kernel that FC4 uses and it works just fine. The url to the patch (it's currently part of Andrew Morton's mm patch tree - but can be applied separately, without any other patches that are part of the mm tree) is 

http://www.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.12-rc4/2.6.12-rc4-mm2/broken-out/areca-raid-linux-scsi-driver.patch

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. install FC4
2. Areca Raid controller is not recognized untill the kernel is rebuild with the 
3. Rebuild the kernel with the patch - and Areca controller is recognized just fine

I agree that it would be nice to have; I have many systems with all storage on a
RAID controller and I am limited to 3ware cards because I won't use anything
that can't be seen from a rescue disk.  I also understand about drifting from
upstream, but given that this driver has very low impact and will most likely
make it into 2.6.13, I wonder if an exception could be made so that it gets onto
the FC4 boot media.

Perhaps Arjan could comment about possible stability impact, since he worked on
the driver.
Comment 3 Dave Jones 2005-05-23 23:04:45 UTC 
After discussion with the scsi maintainer, this driver still needs some work
before its ready for inclusion upstream. Being in -mm is no holy-grail to
stability sadly.

oh, well - that was worth a try. I guess now I'll need to be hacking my own
kernel together with every upgrade - what a pain.
