Hi,

I recently bought Cisco 1921 from Ebay. I configured it and it worked for a while, but it started restarting on its own. I updated the firmware, but it continues again ...

Error: primary instr cache, fields: ,

Try upgrading the firmware of the router.

Hello,

 

if upgrading the firmware as suggested by Leo doesn't help, you also might want to try and open the chassis, and reseat the DRAM.
