I just install 6.0 (out of box) as workstation I followed the instructions with regard to bug ref# 990500-0155 (Getting the Paralell Port Zip Drive working) When I typed insmod ppa ! I get the following /lib/modules/2.2.5-15/scsi/ppa.o: unresolved symbol parport_claim_Rcca15f23 /lib/modules/2.2.5-15/scsi/ppa.o: unresolved symbol parport_register_device_R064ebecf /lib/modules/2.2.5-15/scsi/ppa.o: unresolved symbol parport_unregister_device_R3618c96f /lib/modules/2.2.5-15/scsi/ppa.o: unresolved symbol parport_enumerate_R648d1e26 /lib/modules/2.2.5-15/scsi/ppa.o: unresolved symbol parport_release_R4430d136
This is a known problem with 6.0. There is a knowledge base fix for it located at: http://customer.support.redhat.com/rhoaprod/plsql/xxrh_know_pkg.srch2?p_id=134 This should help you out.
