dmesg (from journalctl -k) including backtrace of hang and usb-storage
debugging
More testing, in response to questions/instructions from the mailing list.
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.
