Hi All, May be SMF is off lining my service during shutdown, but I was not seeing because I was looking at the syslog message which my driver writes as it gets shutdown IOCTL, and the reason for that was syslog service is offline quite before the IOCTL has been made because syslog has dependency on minimal-filesystem.
