This is not a duplicate of bug 438335.

This bug is caused by something wrong with the BARs of 00:0b.0:

  pci 0000:00:0b.0: BAR 1: error updating (0x001001 != 0x000001)
  pci 0000:00:0b.0: BAR 4: error updating (0x40000004 != 0x36850264)
  pci 0000:00:0b.0: BAR 4: error updating (high 0x000000 != 0x000020)
  pci 0000:00:0b.0: BAR 3: error updating (0x001401 != 0x000009)

This report is from a very old kernel, and the dmesg log doesn't contain
quite enough information to tell exactly what's wrong.  If this is still
a problem, and somebody can collect a dmesg log from a current kernel,
I'll take a look at it.

Title:
  "pci BAR 3: " messages on boot

Status in “linux” package in Ubuntu:
  Triaged

Bug description:
  The package in question is linux-source-2.6.31

  The following lines appear at startup instead of the xsplash screen.
  I expected to see the xsplash with the Ubuntu logo however I saw the
  following messages instead.
