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.
I have seen this occasionally too and I'm suspicious that there is something wrong with Walt in android-4.14, seeing the comments I added about the lock problems.
It looks to me like we have a clock sync problem, I'm guessing you can't switch on tracing in time to catch it so we can see how the Walt signal is being built?

Thanks, Leo Yan
