CD-RW drive stopped working on upgrade to 14.04 except after resume from suspend
I had Xubuntu 12.04 running on my machine without issue, and recently formatted and installed a fresh copy of Xubuntu 14.04
The problem is that one of my 3 optical drives (a Cyberdrive CW099D) is now no longer detected on a cold boot, while the other 2 drives are OK.
The drives all work fine in Windows XP and Windows 7, so I do not believe it's a hardware issue.
At boot I noticed:

On resume from suspend (uses S3\STR) I saw:

The CW099D is connected to a JMicron JMB363 SATA/IDE Controller along with the LITE-ON SOHC-5235K.
It seems likely this is a bug, not sure if it's in the JMicron driver or the kernel.
