Up Boards "Freezing"

We've been testing the Up Boards for the past few weeks and have noticed that they "freeze" after a while, (between 30 minutes to a couple of hours)?
We've currently installed Lubuntu 20.10 for our testing... Can anyone suggest any reasons for the "freezing" ?

Ubuntu/Lubuntu 20.10 and Kernel 5.8 has not been tested on UP Board (based on Cherry Trail SoC) and it is not planned to be supported in the future on this specific board.
5.4LTS UP kernel for Ubuntu (supporting Ubuntu 18.04 and Ubuntu 20.04) is going to be released soon and it works correctly on UP Board
Hi DCleri, thanks for the information. A pity about Lubuntu support, we were looking for a "lightweight" solution, but I'm sure we can remove any unneeded packages from Ubuntu.
You can install Lubuntu 20.04 and then our kernel (now 5.0 and soon to be released 5.4), we simply have not tested and not planned to support Ubuntu/Lubuntu 20.10 or 5.8 kernel.
