Hi,

In comment #20 of this bug entry:

https://bugzilla.kernel.org/show_bug.cgi?id=14831

you state:

"Patch for setting dma boundary is mere avoiding condition which is 
causing this
issue. LSI Gen-1 controller does not have 512byte dma boundary limitation. I
have started internal chat with our Firmware engineer. I will update you
findings as and when some imp stuffs are found."

Is this still the case, or is the patch the final fix?

Also, comment #25 in the same thread notes a significant negative write 
performance impact.

Are you seeing this?

I have several machines in production I would like to update, but not if 
there is a better solution to this on it's way.

Regards,

Richard
