The USB mode changes during the flashing, wonder if that is what is
confusing the kernel or not. During the "wake up the Teensy bootloader
mode", I think the USB is talking to /dev/hidraw4, once the device is
programmed, the Teensy (M7) appears as /dev/ttyACM0. Maybe the kernel
can't handle a
FWIW, this total system crash has been isolated to the kernel. Kernel
5.17.5-76051705 crashes. Which was pushed out to apt on, guess what,
May 26, 2022, the date my computer went to hades.
Kernel 5.15.0-37-generic does not crash. Kernel 5.18.2 also crashes,
only if I use TyCommander, but
Followup with SW related items.

own computer is crapping out. Much easier, when it is someone else's.
Pity the machine is not up at the moment. Been busy transferring my
life to an RPI4, which hasn't been as easy as it seems like it should.

Turns out tytools does not have a make uninstall. I made the mistake of
doing sudo make install.
I did compile tytools with the debug flag, but I am not sure if the
optimization was turned off.
Ran valgrind with checking for memory leaks and found quite a few, but,

I am experiencing severe Linux crashes, due to some unknown causes.
They appear to be related to the use of Ty Commander and programming a
Teensy 4.1 in the Arduino IDE environment, but I am not positive. All I
know at the moment, is that the screen freezes and is unresponsive to
