Hello,

similar to
https://lore.kernel.org/all/202602271552.c972ef9e-lkp@intel.com/
we still found we have kernel_reboot-without-warning_in_test_stage by this
change in our tests.

hard for us to understand the connection, and we cannot capture more useful
information from serail. just report FYI what we observed in our tests.


kernel test robot noticed "BUG:kernel_reboot-without-warning_in_test_stage" on:
