Kernel Panic when powering off TB SATA dock

Question

This did not happen in 10.10.1. I'm on my 2013 Mac pro.
New issue with the installation of 10.10.2. If I power on the TB SATA dock and mount an SATA disk then later eject the discs, the shut the power off the TB SATA dock it crashes the OS with a kernel panic. The Mac restarts itself. Yesterday there was no black kernel panic screen but on restart a crash report was generated and sent to Apple. Just now it happened again and there was a kernel panic screen (then the machine self-restarted) but no Apple crash report was generated to be sent out.
I pulled this off the Crash Reporter via Console but they don’t look like crash reports I’ve seen before so tell me what to look for and where and I'll post that.

Answer 1

Any or all of the following third-party system modifications may be contributing to your problem:
SX-Virtual Link
Soundflower
If the panic is recurrent, I suggest you uninstall them, one at a time, according to the developers' instructions, to see whether you can identify which one is at fault. A conflict between modifications may be involved. Reboot and test after each uninstallation.
Back up all data before making any changes.
