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

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, without knowing if -O0 was
