[c-nsp] Processor Memory Parity Errors (PMPE)

[Amol Sapkal]

Hi,

I just had a 7204 going into boot mode due to a PMPE.

router2 uptime is 32 minutes
System returned to ROM by processor memory parity error at PC 0x60658C5C,
addres

The 'show region' command does show the above address as:

0x60008950  0x60703FBF     7321200  IText  R/O    main:text

The 'show stack' command shows the above address too.

What is something new to me is when I run the command 'show bootflash:':



router2(boot)#sh bootflash:

-#- ED --type-- --crc--- -seek-- nlen -length- -----date/time------ name

Error getting file system status (Invalid file header magic number)

router2(boot)#



router2(boot)#cd bootflash:
router2(boot)#
router2(boot)#dir
Directory of bootflash:/

%Error calling getdents for bootflash:/ (Invalid file header magic number)
No space information available
router2(boot)#


What does the above mean? I think I will need to replace the flash?
