[c-nsp] ASR1006 ISSU upgrade fail

[CiscoNSP_list CiscoNSP_list]

Hi Guys,

ASR1006 dual RP/Dual ESP - Followed this guide: http://www.cisco.com/en/US/docs/routers/asr1000/configuration/guide/chassis/issu.html   (Using ISSU to Perform a Consolidated Package Upgrade in a Dual Route Processor Configuration)

Current XE version: asr1000rp1-adventerprisek9.02.01.01.122-33.XNA1 and upgrading to:  asr1000rp1-adventerprisek9.03.05.02.S.152-1.S2

I got to step 5 (issu load version rp 1 file stby-bootflash:asr1000rp1-adventerprisek9.03.05.02.S.152-1.S2.bin), but received the following error:

*May

And the standby RP just continues to reload  (loop), and the above error is printed, then reloads again

Any suggestions are greatly appreciated.
