Hello, I experienced the ext4-randomly-switching-to-read-only issue
with Linux kernel 4.19.5 (from
http://kernel.ubuntu.com/~kernel-ppa/mainline/ ; also with the
previous minor versions) on Ubuntu 18.04 - on two laptops (SATA HDD &
SATA SSD).

I noticed that the only thing I've changed from the default Ubuntu
configuration was enabling *write cache* for the disk with the ext4
root partition. Perhaps this information will help.

Best regards,
Yan Huang (Johnny)
