We got this patch directly from Motorola. Officially Motorola does not 
support Linux, but you can ask Ajit Prem (Ajit.Prem at for 
the latest version of the patch. As far as I know there is a patch 
availeble for 2.6.14 and 2.6.20, but as you have a patch for 2.6.15 
already it should not be to difficult to move the 2.6.14 patch to 2.6.15.

I did not try SCSI on my system I just disabled all devices that I don't 
need, including SCSI. You could try disabling these devices for the 
moment (or build them as modules and load these later by hand) and see 
if that works, or that there are other problems.
If the problem is still there, you could try the Xenomai mailing list
