You seem to have a problem with either the device/adapter or in the 
driver. The backtrace you posted shows that jbd2 (ext4) is still waiting 
on IO that's been submitted to an mpt2sas or mpt3sas adapter (I only 
know that because I recognise their log messages - you should try to 
include relevant details like this when seeking assistance).

The adapter/driver hasn't completed the IO and it looks like the SCSI 
layer is trying to abort it. Depending on the state of the driver and 
hardware your only option might be to reboot (or physically hot remove 
the device if your hardware allows it).

You don't mention the versions of the kernel and driver you're using - 
if the system is in production I would suggest contacting who ever 
normally provides support for the kernel and distribution that you are 
running.

Regards,
Bryn.
