Hi Emmanuel,

Any luck with the testing. I am attaching a copy of my dmesg output which keeps on repeating. In this case, the error seems to be with one dinode.

Let me know if you progress this any further. On another note, we are looking to upgrade the firmware of our LSI raid cards the latest version. Seems like LSI have released a new FW not too long ago.

Thanks

I just received a new server with an LSI controller similar to yours, I'll run some tests but I'd suspect the kernel may be at fault. What is your firmware version exactly?
