Hardware-Related Issues

This section describes hardware-related issues in Oracle Solaris 11.1.

x86: Some Dell Desktops Hard-Hang in UEFI Mode During the Early Kernel Boot Phase (7150035)

A few Dell desktop models, for example, the Precision T1600 and Optiplex 790 models, hard-hang at boot time when booted in the Unified Extensible Firmware Interface (UEFI) mode. This problem is a known Dell firmware issue.

Workaround: To complete the installation, boot the system by specifying the -B uefirt_disable=1 boot attribute.

• To specify this attribute for a one-time boot, edit the GRUB menu at boot time.

• To make the change permanent, use the bootadm command with the change-entry subcommand.

  # bootadm change-entry -i entry-number kargs='-B uefirt_disable=1'

  After installation, you must run the bootadm change-entry command again on the boot environment that the installer created.

  Caution - Make sure to run the bootadm change-entry command before creating any new boot environments to ensure that all new boot environments inherit the same kernel argument strings. Otherwise, you will need to manually change every boot entry that you create. For more information about using the bootadm command to make changes to a particular boot entry, see How to Set Attributes for a Specified Boot Entry in the GRUB Menu in Booting and Shutting Down Oracle Solaris 11.1 Systems.

  Note - These workarounds disable UEFI runtime services, meaning that Oracle Solaris cannot set the system's default boot device. As a result, you might have to manually set the system's default boot device after installation. You can do so by using the system's firmware setup utility, for example, the UEFI Boot Manager.
