Power Management Bugs

Sun Blade 1000 System and Frame Buffer Power Management (4500828)

If a Sun Blade^TM 1000 system is configured with a CD-ROM, or a DVD-ROM, and the monitor and frame buffer are powered off, the system will hang during a panic and a core dump will not be saved.

Workaround: Disable power management of the CD-ROM, or DVD-ROM, on a Sun Blade 1000 system. Follow these steps.

1. Add the following line to the /etc/power.conf file.

   % device-thresholds /pci@8,700000/scsi@6/sd@6,0 always-on

   ---

   Note -

   You must disable power management in the /etc/power.conf file for any additional removable media devices that you have attached to your system. For more information on determining and disabling additional removable media devices, see power.conf(4) and prtconf(1M).

   ---

2. Reboot the system, or type the following on a command line.

   % pmconfig

For more information, see pmconfig(1M).

Frame Buffer Power Management (FBPM) Might Not Be Enabled by Default (4502650)

Frame Buffer Power Management (FBPM) might not be enabled by default in the Solaris 8 10/01 operating environment.

Workaround: To enable FBPM, follow these steps.

1. Type the following on a command line.

   % xset +fbpm

2. Save your CDE session.

The FBPM settings are user-specific and are stored in your home directory. If you login on a system that is not FBPM capable and save the changes to your CDE session, FBPM will be disabled. To avoid disabling FBPM in the future, do not save your CDE session if you are logged in on a system that does not support FBPM. If FBPM becomes disabled, repeat the workaround.
