I have been booting from USB for awhile, and every time I reboot or start after a shutdown, the startup scripts (grub?) get stuck. It seems that the USB drive is unmounted at some point in the script, and I have to physically remove it and put it back in. When I do, everything proceeds normally. It took me awhile to figure out that I had to do this, but now that I know, I find it pretty annoying. I'd like it to start up without me having to do anything but press the power button or reboot from terminal.
I'm an amateur and don't really know where to start on this one. What would be helpful to the community for answering this question?
To start, here are the relevant results from dmesg | less
