Essentially a program I was running for mining did not terminate properly with Ctrl+C it is listed as defunct and cannot be killed, kernel is tainted and normal tricks to disable the port are impossible the dev and sys entries for the device cannot be browsed or interacted with in any form without a lockup of the request. The only solution is to reboot due to the kernel taint as far as I can find so far.

Virtualbox hang problem
A VM just froze and wouldn't close so I had to force it, but the VBox GUI thinks it's running even when I close it.
I manually killed the related process by doing ps aux|grep VirtualBox and found the PID 6191
I killed it with "kill -kill 6191" but it remains open and as "defunct" so I can't restart it because the GUI freezes when I click on it because it thinks it is running still........
