There is some issue with handling the SD card modes.

Something happens with the reader which messes up the USB controller.

This is a kernel oops in the dvb driver. Something didn't get cleaned
up properly when the device(s) went away.
I assume something else happened after the log that you had available
which is not surprising since the kernel was already in a bad state.
It would have been useful to know what error messages you got when grub
was trying to boot.
I suggest upgrading the system because there is likely a kernel fix for
the initial trigger that caused the whole problem. And possibly a dvb
fix as well to avoid the oops. I second the suggestion of testing with
a live boot, but if you're going to upgrade anyway, might as well just
do that.
