I haven't seen any issue on ARCH=parisc. Maybe it's some specific riscv arch issue. I believe that: [auto build test WARNING on next-20201211] [cannot apply to peter.chen-usb/ci-for-usb-next v5.10 v5.10-rc7 v5.10-rc6 v5.10] is not the problem. I based on peter.chen-usb/for-usb-next. Also I can't open the url from kernel test robot report. Maybe there is some temporary issue with server.
