libc6-dbgsym, kodi-dbgsym might make the backtrace more informative.

No patches are needed for 6.1, only for 6.2.

The patch should have zero impact on versions before, but then again 
it's only compile tested ... The patch is made by me and not backported 
from an existing upstream release since there is no release yet 
containing corresponding fixes. (IIRC, the problematic code path is only 
present up to version 470, and there were only new 525 releases so far 
where I took the second part of the 6.2 support from - not needed for 340xx)

In dkms.conf there is a list of patches, remove the 0042 patch from that 
list. Or just get -16 from snapshot.d.o.
