I am willing to test on a Dell r210 with a h200 raid card tomorrow if needed=
.

I destroyed the logical volume and built mps copied from -current (I opened a=
 thread on stable@ a few weeks ago about this) but my "patch" was *nowhere* a=
s big as this.

There's prolly tons of missed stuff... (seems to work though, just wouldn't s=
how me the logical drive so I had to set them to passthrough)

Would that help any ?

The host being half in production now, I'd rather try stuff around only if i=
t helps you guys...

It runs 8.2-RC3 with the sys/dev/mps/ folder from -current, a somewhat patch=
ed conf/files resembling yours, and the makefile to build mps as a module.

Let me know.=
