Hey @majorz, do you guys have any update on this?

[alexgg]

hi @YinonLensor did you try a balenaOS release above v5.3.21+rev4? It contains a v6.6.22 kernel that has already been patched for the problem above.

btw @YinonLensor we don't have a policy of monitoring github issues, so it's better if you contact us through our support channels.
