According to Sun's documentation, a Sun Blade 2500 Red includes a PC-style parallel port. If I build a kernel (any recent 2.6 kernel) with plain parport support (PARPORT_PC=y), there are no kernel messages of any kind related to parport, indicating it didn't find one. If I then add PARPORT_PC_SUPERIO=y the kernel throws a low-level exception and reboots instantly: ... e3d: Found device at 0003:00:02.0 Console: switching to colour frame buffer device 144x56 f008fbfc: ttyS0 at MMIO 0x7fe010003f8 (irq = 23) is a 16550A Console: ttyS0 (SU) console [ttyS0] enabled f0091638: ttyS1 at MMIO 0x7fe010002e8 (irq = 23) is a 16550A Fatal Error Reset CPU 0000.0000.0000.0000 AFSR 0080.0000.0000.0000 AFAR 0000.0008.c004.0000 No I don't intend to use the parport :-) I'm just curious. /Mikael -- To unsubscribe from this list: send the line "unsubscribe sparclinux" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
