SPARC: D-Bus Kernel Heap Corruption When Attempting to Remove a Bus Device (18435472)

On a SPARC system, performing a hotplug operation on a Dual 10-Gigabit SFP+ FCoE CNA card might cause the system to panic.

The following error message is displayed:

panic[cpu0]/thread=2a1054cbc40: kernel heap corruption detected

Workaround: Do not perform hotplug operations such as cfgadm and hotplug on the Dual 10-Gigabit SFP+ FCoE CNA card. You can try to use the attention button to avoid the panic but the button might not be effective.
