Good Evening, 

I have a small Atom based NAS, running build 134, using a Silicon Image 3124 
controller and a raidz zpool with 5 disks - not using anything funky like 
dedup, compression etc - however i seem to be seeing this bug:

And i found this previous post that is exactly what im seeing:

I know there are a fair few bugs reported on the bugdb, but does any one have 
any experience with this card? Or any ideas for how i might work to mitigate 
it? Im not looking for blistering performance but the blocking can cause a 
stuttering when streaming media from the NAS - this doesnt pose an issue most 
of the time, as most of the I/O is pretty light generally speaking. But can be 
annoying none the less. 

Thanks,
