imx6 sata cdrom driver issue

Question asked by Jonathan Bagg on Apr 22, 2015

Mounting a SATA CDROM fails aprox 1/20 times with this error....


root@freescale /tmp$ mount /dev/sr0 test/

UDF-fs: No partition found (1)

mount: mounting /dev/sr0 on test/ failed: Invalid argument


I'm using a Sabre imx6q board, freescale kernel 3.0.35 built with imx6_defconfig and the following extra configs







I've tried several disks and dvd drivers.  They all experience this issue on the Sabra board.  The same disks mount 100% of the time in an x86 machine.


I first noticed the issue on our own imx6d boards running mainline kernel 3.19.  Once in a while the kernel would dump out a backtrace (attached) when mounting.
