Thanks for your reply! I ran the reproducer again on the master branch(commit id: 7726d4c3e60bfe206738894267414a5f10510f1a) and it didn't crash. The reason for not using the latest version is I can't attach more than one gadget at a time using `configfs` and `dummy_hcd`. When I attach the second gadget with a different `udc` it always fails and the kernel message says: ``` [ 1625.254858] Error: Driver 'configfs-gadget' is already registered, aborting... [ 1625.271018] UDC core: g1: driver registration failed: -16 ``` I'm not sure if this is a new feature from version v5.19(v5.18, commit id: 4b0986a3613c92f4ec1bdc7f60ec66fea135991f works very well) or a potential bug, or my mistake... The kernel config is: https://pastebin.com/raw/SLmNMMRd The shell to attach gadgets is: https://pastebin.com/raw/2eDPNip3 The kernel log is: https://pastebin.com/raw/MaDwMQWk Best wishes! Rondreis
