testing 5.38 on cubietruck since yesterday.
everything seems smooth apart from kworker eating CPU issue still there that probably can't be fixed yet (sunxi mainline bug?)
I'll further test and report back other issues before downgrade kernel/headers to 5.32 (4.11.6 is last kernel "kworker bugfree")
thanks for your work. running Debian stretch for server miltipurpose with success on a cubietruck is f*cking awesome
