Greetings all,
I'm receiving a very similar problem to this, and have been doing so ever since
I got three of those same Supermicro AOC-SASLP-MV8 cards six months back. I'm
currently running just one, but that doesn't help.
I've created a software raid5, and it's usable. When this error strikes, it
does recover. IO performance drops to zero for about a minute or three, but it
does come back. Almost always :)
I've tried several kernels since about 2.6.34, vanilla and gentoo alike.
Currently on 2.6.39.2.
I was able to write some 140GB of random data to the array yesterday, and it
didn't fail until I started running a kvm instance and writing to the virtual
disk on it. That kills it every time.
If I don't write large quantities of the data to the array, it remains quite
stable. I'm able to read at excellent speeds.
The disks are Seagate ST31500341AS
I'll attach a log file. Is there anything else anyone needs?
Cheers.
