Crashing The Nexus

I had an interesting day yesterday.  I hit my first bug in Nexus, and it crashed the whole box.  As this happened first thing in the morning I got to spend the rest of the day cleaning up the mess. 

This happened on a 5596UP running 5.1(3)N1(1a)

If you have a config like this:

port-profile type ethernet iSCSI
  switchport mode access
  spanning-tree port type edge trunk
  spanning-tree bpduguard enable
  switchport access vlan 9
  state enabled

port-profile type port-channel Converged
  switchport mode trunk
  switchport trunk allowed vlan 4-5, 11
  switchport trunk native vlan 1000
  spanning-tree port type edge trunk
  spanning-tree bpduguard enable
  state enabled
 
interface port-channel17
  inherit port-profile Converged
  speed 10000
  vpc 17

interface Ethernet1/17
  switchport mode trunk
  switchport trunk native vlan 1000
  switchport trunk allowed vlan 4-5,11
  channel-group 17 mode active

Whatever you do, DO NOT DO THIS:

Nexus5K# en
Nexus5K# conf t
Enter configuration commands, one per line.  End with CNTL/Z.
Nexus5K(config)# int e1/17
Nexus5K(config-if)# inherit port-profile iSCSI

Upon trying to apply the new port profile before either removing the old one, or removing the phsycial interface from the port-channel the management session locked up, and after about 5 minutes a message came up saying the port profile manager process had crashed, and then the "System is going down for REBOOT now!" message.

TAC came back and said I'd hit this bug, but with a trigger not mentioned.
