imx6 sata cdrom driver issue

On arm imx6, running mainline 3.19, mounting a SATA CDROM fails aprox
1/20 times with this error....
root at freescale /tmp$ mount /dev/sr0 test/
UDF-fs: warning (device sr0): udf_fill_super: No partition found (2)
mount: mounting /dev/sr0 on test/ failed: Invalid argument
I've tried several disks and dvd drivers. They all experience this
issue. The same disks mount 100% of the time on an x86 machine. Once
mounted, I can read data without issue. Also tried a HDD on the same
SATA link, no issue.
Sometimes the kernel will dump out the attached backtrace on the mount
command.
