[parisc-linux] B2000 PCI resource problem

Thu Apr 6 13:12:05 MDT 2006

People,

I recently added a Sun dual gigabit, dual scsi PCI card to one of my
B2000s. This board contains 2 cassini chips, and a 53c896, all sitting
behind an Intel (well, Digital) 21154 PCI bridge.

The system works fine, but I'm seeing the following problems:

Whel probing the SCSI part of the board, the kernel spits the
following:

PCI: resource not parented! [2000-2fff]
PCI: resource not parented! [fb000000-fb5fffff]

And if I look at /proc/ioports :

00000000-00001fff : PCI00 Ports
  00000020-0000003e : pic1
  000000a0-000000be : pic2
  000007e0-000007fe : acpi
  00000800-000008ff : sym53c8xx
  00000900-00000907 : ide0
  00000908-0000090f : ide1
  00000d02-00000d02 : ide0
  00000e00-00000e07 : ide0
  00000f00-00000f7f : tulip
00012000-00013fff : PCI01 Ports
  00012000-000120ff : sym53c8xx
  00012100-000121ff : sym53c8xx
  00002000-00002fff : PCI Bus #02
  00002000-00002fff : PCI Bus #02
  00002000-00002fff : PCI Bus #02
  00002000-00002fff : PCI Bus #02
  00002000-00002fff : PCI Bus #02
  00002000-00002fff : PCI Bus #02
  00002000-00002fff : PCI Bus #02
  00002000-00002fff : PCI Bus #02
[... ad nauseam].

Something looks bad here... Does anybody have a clue about this? lspci
output happended at the end of this mail.

Regards,
