Dears,
I have Cisco 1841 Router with no WIC cards and USB.
Image is ipbase and on the flash. When it boots it gives the error and hangs - As suggested I changed the register value to 0x2142 but no change happened.
Following are the capture from the router ...

Use this command for disaster recovery only to recover an image via TFTP.
Monitor variables are used to set up parameters for the transfer.
(Syntax: "VARIABLE_NAME=value" and use "set" to show current variables.)
"ctrl-c" or "break" stops the transfer before flash erase begins.
The following variables are REQUIRED to be set for tftpdnld:
IP_ADDRESS: The IP address for this unit
IP_SUBNET_MASK: The subnet mask for this unit
DEFAULT_GATEWAY: The default gateway for this unit
TFTP_SERVER: The IP address of the server to fetch from
TFTP_FILE: The filename to fetch
The following variables are OPTIONAL:
TFTP_VERBOSE: Print setting. 0=quiet, 1=progress(default), 2=verbose
TFTP_RETRY_COUNT: Retry count for ARP and TFTP (default=18)
TFTP_TIMEOUT: Overall timeout of operation in seconds (default=7200)
TFTP_CHECKSUM: Perform checksum test on image, 0=no, 1=yes (default=1)
FE_PORT: 0= (default), 1
FE_SPEED_MODE: 0=10/hdx, 1=10/fdx, 2=100/hdx, 3=100/fdx,
4=Auto (default)
TFTP_DESTINATION: The flash destination device for the file

Command line options:
-h: this help screen
-r: do not write flash, load to DRAM only and launch image

I also check the flash by plugging into my desktop and it is showing the image - I also formated the flash and again copy the image - but problem remain the same.

Hi Nouman,
Do you get the error message when you eject the CF? If no, then there's a remote possiblity that your IOS could be corrupt. I said "remote" because of the first three line errors:
Correcting the backup nv_flash
*** TLB (Load/Fetch) Exception ***
Access address = 0xffffcfd0
PC = 0xbfc24b00, Cause = 0x8008, Status Reg = 0x30410002
Failure detected during ROMMON start-up tests. Restart ROMMON.
But I think the bootstrap could be corrupt. The easiest to fix this is IF, and only IF, you can boot to a proper IOS then upgrade the bootstrap or ROMMON firmware.
If it still doesn't work, then contact Cisco TAC and arrange to get the appliance RMA-ed.

Hi,
Its a 1841 Router remove the external 128 Mb RAM and reload the Router.
"*** TLB (Load/Fetch) Exception ***"

My Cisco 1841 router had similar errors. Root problem turned out to be an IOS bug with "warm-reboot" enabled. The workaround to remove "warm-reboot" is a workaround for now until new IOS is released.

monitor: command "boot" aborted due to exception
From Cisco TAC support:
There is a couple of bugs about the issue:
Router crashes aftr upgrade to 15.1(4)M3 when "warm-reboot" CLI is cfg'd
Externally found severe (Sev2) bug: D-Duplicate
3845 Fails to Boot 15.1(4)M3
Externally found severe (Sev2) bug: D-Duplicate
Duplicate of:
Router getting reloads with "warm-reboot" cli
Internally found severe (Sev2) bug: R-Resolved
This will be fixed in 15.2(3)T and 15.1(4)M4 which is expected to be released on March 30. The workaround is to remove the "warm-reboot" command.
Router(config)#no warm-reboot
Router(config)#exit
Router#write
