Sometimes mount hangs forever in openat instead. I guess probably some kernel thread is getting stuck for reasons not directly related to mount, and mount is hanging as a result. I built with 5.7-rc7 and CONFIG_USB_STORAGE_DEBUG enabled. I got a hang in openat; I've attached kernel logs. usbmon shows a similar bulk input transfer which never completes (even after waiting several minutes); I can attach that output if it's helpful. -- You are receiving this mail because: You are the assignee for the bug.
