I'm having problems with my own compiled v19.07.3 build and I'm thinking of going back to the master trunk. Master is obviously not recommended for stability however. I was just wondering how many people that compile their own firmware use master trunk as their daily driver.
I find master better for x86_64 than 19.07 and perfectly stable as far as I'm concerned
I compile off master for x86_64 router and ath79 APs. Generally stable although sometimes there is breakage that is fixed within a few hours to a few days. I like having the freedom to compile ath79 with kernel 5.4 and gcc 9.3, strip out unused/unwanted features and have resulting images that are lean, fast and current.
I use master for the last couple of years on mvebu, mainly to-do some longterm testing myself for my packages. Yet i only encountered one issues in all those years, maybe lucky?
