SPARC: Stopping the System by Using Keyboard Sequences Might Cause a System Panic (5061679)

If you attempt to stop the system by pressing keyboard sequences such as Stop-A or L1-A, the system might panic. An error message similar to the following example is displayed:

panic[cpu2]/thread=2a100337d40: pcisch2 (pci@9,700000): 
consistent dma sync timeout

Workaround: Do not use keyboard sequences to force the system to enter OpenBoot^TM PROM.
