Applying a Kernel Patch to FreeNAS for LSI MegaRAID 9260-8i

[zyphex]

I'm posting this in the n00b forum because I'm lost on how to do this and I'm not the most experienced with Unix-like operating systems.

I have a LSI MegaRAID 9260-8i in my freenas box. From time to time, the controller will spontaneously timeout and lock up the operating system. The specific error appears like -

mfi0: COMMAND 0xffffff8000b216c8 TIMEOUT AFTER 150 SECONDS
mfi0: COMMAND 0xffffff8000b216c8 TIMEOUT AFTER 180 SECONDS
mfi0: COMMAND 0xffffff8000b216c8 TIMEOUT AFTER 210 SECONDS
mfi0: COMMAND 0xffffff8000b216c8 TIMEOUT AFTER 240 SECONDS
mfi0: COMMAND 0xffffff8000b216c8 TIMEOUT AFTER 271 SECONDS

After updating FreeNAS, the firmware on my raid controller, and doing extensive research, I found out the problem isn't due to faulty firmware, a driver, or a faulty card, but is relatively common with FreeBSD and LSI controller cards.

As described here -

My specific question is - how do I apply the kernel patch file that was posted on the FreeBSD site (testperc.c)

Would it use something like the patch command? And does that require a specific target file to patch?

I think you can give the 8.3.0 ALPHA a try, it has FreeBSD 8.3 and should have the fix already...
