May be you need to use IoRaiseHardError or IoRaiseInformationalHardError?

First question: no, not really, but see IoRaiseHardError and
IoRaiseInformationalHardError.
Second question: log errors to the system error log.

You cannot, unless you have a helper user-mode code which will do this.

If not, what are the message notification for kernel mode dll ?

IoRaiseInformationalHardError can help, but it is rather limited.

FYI, IoRaiseHardError and IoRaiseInformationalHardError only exist in
ntddk.h, not in wdm.h.
