Solution 1571215.1 : Analysis of error message "WARNING: consconfig: cannot find driver for screen device"

Applies to:

SPARC T4-2 - Version All Versions to All Versions [Release All Releases]
Oracle Solaris on SPARC (64-bit)

Symptoms

A Sparc T4-2 System reported the following error message during boot:

Jan 16 15:04:45 myhost consconfig_dacf: [ID 615089 kern.warning] WARNING: consconfig: cannot find driver for screen device /pci@400/pci@1/pci@0/pci@0/pci@0/display@0

Cause

Root cause of the message was a missing driver package for the onboard Graphics Device.

Solution

1) Locate the affected device

Check "prtdiag -v" for a device with the same path as in the error message:

                        /pci@400/pci@1/pci@0/pci@b/pci@0/usb@0,2

In this Example the path matches the T4-2 onboard Display device. The affected Graphics Device may as well be an add-on card.
Document 1005907.1 contains information about onboard Display devices and their paths in SPARC Systems.

2) Determine which driver is needed for screen device on path "/pci@400/pci@1/pci@0/pci@0/pci@0/display@0"

Locate path /pci@400/pci@1/pci@0/pci@0/pci@0/display@0 in /etc/path_to_inst

# grep "/pci@400/pci@1/pci@0/pci@0/pci@0/display@0" /etc/path_to_inst

"/pci@400/pci@1/pci@0/pci@0/pci@0/display@0" 0 "ast"

The driver needed for this Graphics Device is "ast".

3) Determine Operating System Version

#cat /etc/release
Oracle Solaris 10 8/11 s10s_u10wos_17b SPARC
Copyright (c) 1983, 2011, Oracle and/or its affiliates. All rights reserved.
Assembled 23 August 2011

4) Consult the Oracle Solaris 10 8/11 Package List for the package name containing the driver "ast"

SUNWastfb - Device driver for AST graphics

Note: On a Solaris 11 System the package name is "driver/graphics/ast"

Where to find the Package lists?

For Solaris 11 Releases, go to Oracle Solaris 11 Documentation

For Solaris 10 Releases, go to Oracle Solaris 10 Documentation

For Solaris 9 and older Releases, go to Legacy Solaris Documentation

5) Determine if the package "SUNWastfb" is installed

On Solaris 10 and older Releases:

# pkginfo -l SUNWastfb

On Solaris 11 Releases:

# pkg info driver/graphics/ast
