Interesting, denials can result in strange behaviors/bugs/crashes but I
am going to atm just focus on fixing the apparmor confinement. Which
rule addition did you try?
If you haven't tried it yet, does using
/usr/local/lexmark/** Ux,
instead of
/usr/local/lexmark/08zero/bin/printdriver rix,
result in a different behavior?
Also can you provide some timestamps, and md5sums of the cache file?
do the following after reboot, and then again after the apparmor_parser command
ls -l /etc/apparmor.d/cache/usr.sbin.cupsd
md5sum /etc/apparmor.d/cache/usr.sbin.cupsd
