Module Name: src
Committed By: mrg
Date: Sat Sep 15 08:48:18 UTC 2018
Modified Files:
src/sys/ddb: db_command.c
Log Message:
call spl0() before cpu_reboot(), so that there's a chance that:
- interrupts can work afterwards
- this also means if IO stalls, serial break might work again.
this mimics how reboot(2) ends up calling cpu_reboot().
