Dear Linux folks,
Linux 5.4.39 reports the watchdog messages below on a Dell PowerEdge T630 with 12x E5-2603 v4 @ 1.70GHz.
DMI: Dell Inc. PowerEdge T630/0NT78X, BIOS 2.5.4 08/17/2017
``` handsomejack:~$ more /proc/version Linux version 5.4.39.mx64.334 (root@lol.molgen.mpg.de) (gcc version 7.5.0 (GCC)) #1 SMP Thu May 7 14:27:50 CEST 2020 handsomejack:~$ grep TCO /boot/config-5.4.39.mx64.334 CONFIG_NETCONSOLE=m CONFIG_NETCONSOLE_DYNAMIC=y # CONFIG_SP5100_TCO is not set CONFIG_ITCO_WDT=y CONFIG_ITCO_VENDOR_SUPPORT=y CONFIG_NV_TCO=y # CONFIG_INTEL_SMARTCONNECT is not set # CONFIG_EXTCON is not set handsomejack:~$ dmesg --level=err [ 11.618887] watchdog: iTCO_wdt: cannot register miscdev on minor=130 (err=-16).

Together the error and success messages are from the same module are confusing me a little. How can I find out the legacy watchdog module?
Kind regards,
Paul
