Hi, thanks for your answer. I don't really know how to reproduce it. My guess is that the block size or some checking code changed between before and after the upgrade.
For additional logs, I would be happy to add additional logs. I think I have added all logs related to the problem however I would add more if needed and given the command to produce them. The problem is still present as given by the following command: pablo@compute:~$ dmesg -T | tail [Mon Jun 1 23:59:20 2020] bcache: register_bcache() error : failed to register device [Mon Jun 1 23:59:20 2020] bcache: bcache_device_free() bcache device (NULL gendisk) stopped [Mon Jun 1 23:59:21 2020] bcache: bcache_device_init() nr_stripes too large or invalid: 3485497471 (start sector beyond end of disk?)
