OK. Here it is:
Sep 3 00:33:28 linux kernel: 0x378: FIFO is 16 bytes Sep 3 00:33:29 linux kernel: 0x378: writeIntrThreshold is 8 Sep 3 00:33:29 linux kernel: 0x378: readIntrThreshold is 8 Sep 3 00:33:29 linux kernel: parport0: PC-style at 0x378 (0x778) [PCSPP,TRISTATE,COMPAT,EPP,ECP] Sep 3 00:33:29 linux kernel: parport0: irq 7 detected Sep 3 00:33:29 linux kernel: parport0: Printer, Hewlett-Packard HP LaserJet 6P Sep 3 00:33:29 linux kernel: lp0: using parport0 (polling).
Here are the contents of the parport directory in /proc:
:::::::::::::: /proc/sys/dev/parport/parport0/autoprobe :::::::::::::: CLASS:PRINTER; MODEL:HP LaserJet 6P; MANUFACTURER:Hewlett-Packard; DESCRIPTION:Hewlett-Packard LaserJet 6P Printer; COMMAND SET:PJL,MLC,PCLXL,PCL; :::::::::::::: /proc/sys/dev/parport/parport0/autoprobe0 :::::::::::::: :::::::::::::: /proc/sys/dev/parport/parport0/autoprobe1 :::::::::::::: :::::::::::::: /proc/sys/dev/parport/parport0/autoprobe2 :::::::::::::: :::::::::::::: /proc/sys/dev/parport/parport0/autoprobe3 :::::::::::::: :::::::::::::: /proc/sys/dev/parport/parport0/base-addr :::::::::::::: 888 1912 :::::::::::::: /proc/sys/dev/parport/parport0/devices/lp/timeslice 200 :::::::::::::: /proc/sys/dev/parport/parport0/dma :::::::::::::: -1 :::::::::::::: /proc/sys/dev/parport/parport0/irq :::::::::::::: -1 :::::::::::::: /proc/sys/dev/parport/parport0/modes :::::::::::::: PCSPP,TRISTATE,COMPAT,EPP,ECP :::::::::::::: /proc/sys/dev/parport/parport0/spintime :::::::::::::: 500
As far as I can see, although IRQ 7 is detected, it is not used, so I don't see how starting parport with irq=none would help. Could CONFIG_PARPORT_PC_FIFO actually improve matters in such a situation?
