SPARC: Panics That Occur During Suspend and Resume Cycles Might Cause the System to Hang (5062026)

A system panic that occurs while you are performing a suspend-and-resume ( cpr) cycle might cause the system to hang. More typically, this problem is observed in Sun Blade^TM 2000 workstations that have the XVR-1000 graphics accelerator installed. Rarely, other SPARC based systems might similarly hang during a panic. When the panic occurs, the core dump is not saved, and no prompt appears on the console. The problem might be more prevalent if the kernel debugger (kadb) is active.

Workaround: To restore the system to a usable state, manually reboot the system.
