>Category:
>Environment:
System : OpenBSD 7.9
Details : OpenBSD 7.9 (GENERIC.MP) #222: Wed May 6 18:07:56 MDT
2026
[email protected]:/usr/src/sys/arch/arm64/compile/GENERIC.MP
Architecture: OpenBSD.arm64
Machine : arm64
>Description:
When rad is enabled, the system panics at shutdoen/reboot, no orderly
reboot possible
>How-To-Repeat:
rcctl enable rad
rcctl start rad
shutdowen -r now
... panic
... reboot
rcctl disable rad
rcctl stop rad
... panic
... reboot
rcctl check rad
rad (failed)
shutdown -r now
... ok
>Fix:
disable rad
