I am not surewhy you suspect your driver if it works with 1.15, I would
have expected the kernel to be the cause.

I am not sure how to deactivate the data cache. Can it be done without
a reboot or do I need to edit the mint.cnf ?

Did I read that there has been a change in the cache sizes or block sizes
or something like that ?
