Here's my case, using opensuse 10.3, asus P4PE motherboard, 2.4GHz P4, 1 GiB
RAM: the printer works fine without any option passed to parport_pc
(parport0: PC-style at 0x378 (0x778), irq 7, dma
3[PCSPP,TRISTATE,COMPAT,ECP,DMA]), until the module is reloaded. After that,
any access to /dev/lp0 hangs, regardless of passing dma=none (I added
the line "options parport_pc dma=none" to /etc/modprobe.conf.local). I got this
once:
Mar 15 16:19:27 linux kernel: pnp: Device 00:09 disabled.
Mar 15 16:19:27 linux kernel: parport 0x378 (WARNING): CTR: wrote 0x0c, read
0xff
Mar 15 16:19:27 linux kernel: parport 0x378 (WARNING): DATA: wrote 0xaa, read
0xff
Mar 15 16:19:27 linux kernel: parport 0x378: You gave this address, but there
is probably no parallel port the
Mar 15 16:19:27 linux kernel: parport0: PC-style at 0x378 [PCSPP,TRISTATE]
Mar 15 16:19:27 linux kernel: pnp: Device 00:09 activated.
Mar 15 16:19:27 linux kernel: parport_pc 00:09: reported by Plug and Play ACPI

Mar 15 16:19:28 linux kernel: lp0: using parport0 (interrupt-driven).
, the other times the syslog messages were normal:
Mar 15 16:57:35 linux kernel: pnp: Device 00:09 activated.
Mar 15 16:57:35 linux kernel: parport_pc 00:09: reported by Plug and Play ACPI

Mar 15 16:57:44 linux kernel: lp0: using parport0 (interrupt-driven).
Mar 15 16:58:33 linux kernel: lp0: ECP mode
The BIOS setting is EPP/ECP mode, the IO chip is a Winbond one, EFER=0x2e
key=0x87 devid=87 devrev=08 oldid=00 type=unknown.
This is irritating as both yast and the vmware configuration script cause
parport_pc to be reloaded.
