Indeed.
The unit has eMMC issues as well. I've been trying to stabilize the wifi, but have yet to find a solution.
I'm honestly out of ideas on the kernel side and am thinking this might be u-boot related in some way, but I won't know until I get it booting on current mainline.
I've since updated the patching so that the unit now uses the rtl8821cu driver from; https://github.com/morrownr/8821cu-20210916
git pull
and either upgrade the kernel on the unit or create a new img.

For reasons unknown it appears to be more stable.
With the inclusion of u-boot v2024.01 and a series of fixup patches for rtl8822/21cu this should no longer be an issue.
