The kernel panics in 5.5 seem to be related to zram. I had swap set up on zram since day one, still on kernel 5.4, but I wasn't getting any kernel panics back then, only Xorg crashes and difficulties waking up from sleep. Now even if I completely disable compositing I still get kernel panics, and the likelihood of me getting one seem to be increasing with the memory usage. Replacing zram swap with traditional on-disk swap allows me to avoid kernel panics no matter the memory use, but it is much slower than zram and I don't want to wear out eMMC. And I still haven't had time to figure out debugging over UART...
