How did you trigger this error ? Is there a reproducer ? Details please ...
While Scanning a lenovo usb2.0 udisk， not 100 % reproduce
Can you include Linux
lsusb -vvv
output for this device and include that information in the commit message ? (or the U-Boot info below, that works too, just please add it into the commit message, it is important for future reference).
OK， I will add lsusb -vvv Linux udisk message and crash dump info to commit message
Thank you
This is log.

Where does the crash point to in code, can you disassemble the PC pointer ? (or maybe you can use scripts/decodecode I think)
OK， I will add EPC pointer disassemble to commit message
This part probably doesn't need to be in the commit message. I'd like to know where the crash occurred in the code.
