SubjectHard crash when trying to use PCI parallel port card
With the purpose of having two printers connected to my Linux server I
bought a PCI (single port) parallel port card thinking that installation
would be straightforward.

Parport was already compiled into the kernel (version 2.2.17), and lp is
a module.

After looking at the output from 'lspci -vvx' (see below) I added
'append="parport=0x278,auto parport=0x7c00,11"' to lilo.conf and
rebooted, this far everything was looking good since parport even
managed to retrieve the printer info from the new card (lp1):

<text during bootup>
parport0: PC-style at 0x278 [SPP,PS2,EPP]
parport_probe: failed
parport0: no IEEE-1284 device present.
parport1: PC-style at 0x7c00, irq 11 [SPP,PS2]
parport_probe: succeeded
parport1: Printer, Hewlett-Packard HP LaserJet 1100


Now, as soon as I try to print to /dev/lp1 the box locks up hard
(without any oops messages), moving the printer to lp0 and changing only
the device in /etc/printcap allows me to print just fine.

By looking at the windows drivers provided with the card I came to the
conclusion that the onboard chip was an Oxford Semiconductor OX16PCI954
which as far as I could understand is documented in
http://www.oxsemi.com/products/uarts/ox16pci954/ox16pci954ds.pdf. I've
also searched the previous LKML archives for any posts about this
chipset and all I could find was an older post
(http://lists.insecure.org/linux-kernel/2000/Sep/0071.html) from Tim
Waugh <twaugh@redhat.com> claiming to add support for this chipset.
Looking at 2.2.18-pre25 I couldn't see that the patch had been included
though and as far as I could understand (with my limited knowledge of C)
the patch only added the PCI id's to the kernel.

Now, what can I do to solve this problem? (If any info is missing,
please just ask)


Thanks in advance,
David Härdeman
