[Bug 180390] Parallel port printing does not function with SLED 10 RC2
https://bugzilla.novell.com/show_bug.cgi?id=180390#c88
--- Comment #88 from Johannes Meixner
From several user reports (i.e. from all user reports which I got up to now): The parport does not work out-of-the-box after system installation which means it doesn't work if nothing is specified in modprobe.conf because this are the "parport" lines in my modprobe.conf after a openSUSE 10.3 default installation:
alias parport_lowlevel parport_pc # options parport_pc io=0x378 irq=none,none # options parport_pc io=0x378,0x278 irq=none,none ------------------------------------------------------------------------- Furthermore comment #82 seems to show that when "irq=7" is specified it leads to "DMA 7" but "IRQ" != "DMA" so that according to comment #79: "Could this simply be a misallocation of the DMA channel by the kernel?" In any case I don't think it is a good idea to provide manually set options to the user/admin but later ignore them in the kernel. Here is seems the kernel tries to apply too much of its own additional "intelligence" when values are specified in modprobe.conf. Even if there would be whatever broken printer setup tool which writes nonsense to modprobe.conf, then this broken tool must be fixed but as far as I know there is no such tool. I would even like to have a "mode" option in modprobe.conf so that in case of trouble the user could enforce all parport parameters to the kernel e.g.: options parport_pc io=0x378 irq=7 dma=3 mode=ecp -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
