I'm out of ideas/clues trying to resurrect my printer after I "upgraded"
from SuSE 7.2 (2.4.4 kernel) to SuSE 8.0 (2.4.18 kernel). My system is
a Compaq Presario 5008US, about 1.5 years old, 386MB RAM, 40 GB disk,
an 800 Mhz Celeron,... nothing fancy.
The parallel port is at 0x378, irq=7, dma=3, io_hi=0x778 and fully
functional from Windoze. BIOS option are COMPAT, BI-DIR, EPP and ECP
with ECP being the default.
Printing was a no-brainer under 2.4.4. I used the Epson EKPD drivers from
their web-site to drive a Stylus Photo 820 (great results!). The relevant
messages from the boot log were:
May 27 22:26:49 timesink kernel: parport0: PC-style at 0x378 (0x778)
May 27 22:26:49 timesink kernel: parport0: irq 7 detected
May 27 22:26:49 timesink kernel: parport0: cpp_daisy: aa5500ff(98)
May 27 22:26:49 timesink kernel: parport0: assign_addrs: aa5500ff(98)
May 27 22:26:49 timesink kernel: parport0: Printer, EPSON Stylus Photo 820
May 27 22:26:49 timesink kernel: lp0: using parport0 (polling).
After the "upgrade" I get:
Jul 7 15:32:11 timesink kernel: parport 0x378 (WARNING): CTR: wrote 0x0c,
Jul 7 15:32:11 timesink kernel: parport 0x378 (WARNING): DATA: wrote 0xaa,
Jul 7 15:32:11 timesink kernel: parport 0x378: You gave this address, but
there is probably no parallel port there!
Jul 7 15:32:11 timesink kernel: parport0: PC-style at 0x378 [PCSPP,TRISTATE]
At this point /dev/lp0 is a functional equivalent of /dev/null
The /proc/... files for parport are all devoid of signs of functionality.
I have search the parport archives and tried probably all suggestions
to no avail. Among the things I tried were:
1. Use the most recent RedHat parport and parport_pc sources: they are nearly
identical, load fine and produce the same unsatifactory result.
2. Go back to use the 2.4.4 modules for parport(_pc) under the new kernel:
same difference (slightly different messages, but no printer).
3. Tried to compile with different config-options:
# CONFIG_PARPORT_PC_SUPERIO is not set (<<< setting it make no diff)
# CONFIG_PARPORT_AMIGA is not set
# CONFIG_PARPORT_MFC3 is not set
# CONFIG_PARPORT_ATARI is not set
# CONFIG_PARPORT_SUNBPP is not set
# CONFIG_PARPORT_OTHER is not set (<<< setting it make no diff)
4. I tried numerous variants of the /etc/modules.conf file (suggested here
and elsewhere): no luck
5. I noticed that without io=0x378 given at either modules.conf or
explicitly at insmod-time, the parport_pc will not load, claiming
the device is busy. I guessed that the superio-chip in my system
is miss-configured by some other module, so I tried to load
parport_pc as early as possible: no luck
here is a list of the loaded modules:

6. I tried all bios options for the parallel port - made no difference.
At this point, I'm out of ideas. I figure that the parallel port is
really not there due to some module messing with the superio chip.
But I'm not a kernel hacker and have no idea how to figure this out.
Any suggestions (short of printing only in Windoze) are highly

PS: SuSE's installation support (I bought the 'professional' version)
excludes help regarding printers. They were most unhelpful - this
is definitely the last distribution I ever bought from them.
