Description
I'm using avrdude to program an Atmel microcontroller. It uses an USB serial port.
The chip is succesfully programmed but then I get a crash. This is reproductible. I looked at the tty using the appropriate KDL command and it appears to be fine.

I am looking closer at the code and noticed that the tty KDL command does not work as I thought. You can ignore the info in DSC_2025.JPG which is not about the TTYs involved in the crash.

Added a new capture showing the backtrace and the TTYsfound in the cookie. What's strange is the address passed to tty_notify_if_available and printed in the backtrace does not look valid. What could be happening here? It should be one of the two TTYs found in the cookie?

Fix merged in hrev55558
It only happens with the usb_serial driver. No problems with pc_serial.
