If you suspect that the partition tables are corrupt, it would be a good
idea to fix that first. If the kernel misbehaves after that, please update
it. I would also check that the installed lvm2 package is up-to-date.
The log message above says that queue_max_hw_sectors(q) is zero. But the
"bio too big" error was removed in v4.3, so I'm disinclined to pursue
that.
If I had to guess, I'd say that some component is still offline/inactive.
You might learn more from 'lvs --all', 'pvdisplay', 'vgdisplay' etc.
