I think you need to read this from the bottom up:
"Corruption of in-memory data detected. Shutting down filesystem"
so XFS calls xfs_do_force_shutdown to shut down the filesystem. The
call comes from fs/xfs/xfs_trans.c which fails, and so reports
"Internal error xfs_trans_cancel".
In other words, I would look at the memory corruption first. This
_could_ be a kernel problem, but I would suggest starting with an
extended memory check, it smells to me of a failing chip.
Just my 2d worth!
