I recently upgraded to Mandriva 2010.0 and in doing so lost ability to use my parallel printer. After many hours of debugging effort and finding nothing in logs or hardware/driver error messages, I went on a hunch that it could be related to the kernel. So I rolled back to the 2009.1 kernel 2.6.29 and printing returned. I don't know how to proceed with determining the root cause as I cannot find any error in the logs or differences in hardware detection and module loading. I don't even know the hierarchy of the modules involved (parport, parport, pc, lp, and ppdev). Should I start diffing those modules and see if I get lucky applying hacking 101 techniques? Please CC me (smeisner@charter.net) if you have any suggestions (except for buying a new printer). Thanks, -- Steve Meisner
