**If the router does not experience the continuous loop after following the troubleshooting steps above, then

the problem may have been caused by a mis−seated network module. It is recommended that you monitor the

router for 24 hours to be sure that the router continues to function without experiencing the issue again.

Bus Error Exception

Here is an example of a bus error exception message:

** System received a Bus Error exception ***

signal= 0xa, code= 0xc, context= 0x61c67fc0

PC = 0x6043904c, Cause = 0x2420, Status Reg = 0x34018002

SegV Exception

If you don't power−cycle or manually reload the router, the show version output displays the following:

Router uptime is 2 days, 3 hours, 5 minutes

System restarted by error − a SegV exception, PC 0x80245F7C

System image file is "flash:c2600−js−mz.120−9.bin"

The following lines may also be present in the console logs:

*** System received a SegV exception ***

signal= 0xb, code= 0x1200, context= 0x80d15094

PC = 0x80678854, Vector = 0x1200, SP = 0x80fcf170

Refer to SegV Exceptions for more information regarding this issue.

%ERR−1−GT64010

This is an example of a %ERR−1−GT64010 error:

%ERR−1−GT64010: Fatal error, PCI Master read

cause=0x0120E483, mask=0x0CD01F00, real_cause=0x00000400

bus_err_high=0x00000000, bus_err_low=0x04080000, addr_decode_err=0x14000470

Corrupt Software Image

When booting, a router may detect that a Cisco IOS software image is corrupt, return the "compressed image

checksum is incorrect" message and attempt to reload, reporting the event as a software−forced crash:

Error : compressed image checksum is incorrect 0x54B2C70A

Expected a checksum of 0x04B2C70A

*** System received a Software forced crash ***

signal= 0x17, code= 0x5, context= 0x0

PC = 0x800080d4, Cause = 0x20, Status Reg = 0x3041f003

This behavior can then repeat indefinitely, or the router may drop to the ROM monitor.

This can be caused by a Cisco IOS software image that has actually been corrupted during transfer to the

router, in which case it can be resolved by loading a new image onto the router. Use Cisco Search to find a

ROMmon recovery method for your platform.
