Event 'line_retrain' is invalid for the current state 'boot_init':vdsl

[mR_Slug]

Had a working config, router and vdsl modem were fine. Now I get:

%VDSL_DAEMON-3-MODEMRESET: VDSL Modem reset. Reloading the modem.
%VDSL_DAEMON-3-MODEMRESET: VDSL Modem reset. Reloading the modem.
%VDSL_DAEMON-3-MODEMRESET: VDSL Modem reset. Reloading the modem.
%SM-4-BADEVENT: Event 'line_retrain' is invalid for the current state 'boot_init':

vdsl_daemon_sm VDSL 0/3/0
-Traceback= 30C3E128z 30C3EBB4z 30032B5Cz 30032B40z

I've tried replacing the modem, same problem.

Any Ideas?

Hello,

this can be caused by anything from firmware to hardware. I agree with @marce1000 that we need more information. Post the output of:

sh ver

sh hardware

Sorry, forgot to post the config. its a 2901 with an EHWIC-VA-DSL-M in slot 3.

Tell me if you want the full output posted. Attached is the config with passwords/keys removed. Is there supposed to be firmware for the modem in the output of dir?

Ah-ha! the dsl.bin file was missing so i copied the image using copy http://location flash0:. Followed these instructions https://www.cisco.com/c/en/us/support/docs/long-reach-ethernet-lre-digital-subscriber-line-xdsl/lre-vdsl-long-reach-ethernet-very-high-data-rate-dsl/118982-config-vdsl-upgrade-800-router-00.html. However i did have to issue a reload/reboot to get it to take. Otherwise show controller vdsl 0/3/0 gave nothing.

Now how did this happen? Well... A box fell on my USB console cable and broke, so i used a serial console cable, but i left it at the enable prompt. Linux's screen produced garbled output, and I thought the serial port was toast. Now what i had forgot was that a getty terminal was configured on that serial port of the PC. This caused the server to kernal oops and screwed the router. My hostname is 'dsl' , and the image was dsl.bin. Somehow the pc got the dsl prompt and somehow in all the chaos deleted dsl.bin. Not noticed until power loss. Talk about an edge case!
