Hi. After upgrade to v7.2 my LMT LTE18 (RBD53G-5HacD2HnD&EG18-EA) randomly reboots 3-4 times per day with kernel error messages in the Log:
router was rebooted without proper shutdown, probably kernel failure
kernel failure in previous boot

FYI.
I have the same problem. Running 7.2.3.
I have ulso updated to 7.3.1, but after a day or two i see that it is back on 7.2.3. Maybe LMT somehow rolls it backā¦
Anyway, with both versions it randomky reboots
same issues on 1036 with 7.2.1 and 7.4
same issues on 1076 with 7.4.1
Simply do a downgrade to the stable version for your device and open a ticket on Mikrotik support to receive support.
Regards.
Can you downgrade from 7.x to 6.x?
