Hi all,

I can reproduce the warning from WALT function walt_fixup_busy_time() in Android kernel 4.14 on Hikey960 board.

The detailed log is as below. To trigger this issue, I usually reboot the board for multiple times: 'while true; do adb reboot; sleep 30; done' and at the boot time this issue can be reproduced.

Before dig into this, I share the log to check in case we have the fixing yet for it.

Thanks, Leo Yan
