What is the error “BUS_HDR_ERR: EARL L2 ASIC #0: Dbus Hdr. Error occurred. Ctrl1 0x930D0EBD” in Cisco 6500 Series Switch? – part 2

As mentioned in my previous post the error “BUS_HDR_ERR: EARL L2 ASIC #0: Dbus Hdr. Error occurred. Ctrl1 0x930D0EBD, Jun 7 16:47:27.446: %EARL_L2_ASIC-DFC9-4-DBUS_HDR_ERR: EARL L2 ASIC #0: Dbus Hdr. Error” means that the EARL L2 ASIC detected an invalid header on DBus, and it could be a faulty Cisco Catalyst 6500 Series 8-Port 10 Gigabit Ethernet Module.
Initially I removed the defective module out of the chassis and firmly reinserted the module in the slot to ensure the module is well seated in the slot.
After reinserting the module it worked well and when I checked logs with the IOS command “ Show module” the module was passing all the test and no error was detected.

After a week when I again checked the module the error reappeared. Since we had a valid Smartnet contract with Cisco we opened a TAC case with Cisco, an RMA was created and the defective module was replaced. I would siege this opportunity to emphasize the importance of having valid smartnet contracts with Cisco System is very handy and proves to be a worth investment.
