RT86U - problem after last Entware update.

[miazza]

Hi all, I have updated my RT86U with last amtm , diversion and all the relevant scripts.
Also I have updated enware to latest version.

Now I see the following anomalous behaviours:
- In webif CPU, Internet Traffic and RAM bars are stuck at about 40%
- all cron jobs are not executed
- spdmerlin not working and relevant webui page not updated
- same story for uiDivStatus
- in SSH I can only execute amtm while if I try any command like "reboot" I get the following:

/sbin/reboot: line 1:ELF: not found
/sbin/reboot: line 10: : not found
/sbin/reboot: line 107: syntax error: unexpected ";"

A reboot from webif works but after few minutes from reboot the problem appears again.
I tried to power cycle the rooter without success

I tried a full deep factory reset but after restoring the same set-up I again have the problem.

Am I alone with this issue ?

thanks
