>Organization:
>Environment:
NetBSD 7.1 (GENERIC.201703111743Z) amd64
>Description:
I would get the 'DRVGETEVENT failed: Resource temporarily unavailable' error frequently while I was playing around with writing some scripts for devpubd. While doing so I would frequently start and stop the service.
>How-To-Repeat:
# devpubd -f
# CTRL-C
# devpubd -f
>Fix:
I believe its because it fails to close /dev/drvctl. This patch against 7.1 works for me, unfortunantly I couldn't get current to compile so I gave up.
