comment:1 Changed 8 years ago by anonymous

Seems to occur when issuing the following command:

cat /proc/sys/dev/dslmod

comment:2 Changed 8 years ago by sst@…

Confirmed on my modems, an echo to dslmod will generate the error above in dmesg, and the ADSL will never be in sync (avsar_modem_training stay on idle)

comment:3 Changed 7 years ago by florian

  • Resolution set to wontfix
  • Status changed from new to closed

This certainly should not crash, but I do not see a reason to issue a cat /proc/sys/dev/dslmod.

comment:4 Changed 2 years ago by jow

  • Milestone changed from Attitude Adjustment 12.09 to Barrier Breaker 14.07
