--- Begin Message ---Package: alsa-utils Version: 1.0.28-1 Severity: critical Justification: breaks unrelated software Dear Maintainer, I might have found an issue with USB-MIDI devices * What led up to the situation? using pygame.midi to spit out note_on's to an Akai APC mini (in an endless loop, without sleep()s, to test/fuzz it) * What was the outcome of this action? General protection fault in dmesg lsusb hangs... * What outcome did you expect instead? Flicker of a led / Akai device hangs? Apparently the USB-Midi device froze and the system did not handle that gracefuly?
