dmesg on boot

As I have already said in the other bugzilla, when my I do:
  xset dpms force standby
  echo "low" > /sys/class/drm/card0/device/power_profile
the first time I have this message:
NMI: PCI system error (SERR) for reason a1 on CPU 0.
Dazed and confused, but trying to continue
but, if I follow you suggestion this disappears:
You can disable the PCIE lane changes by removing the
call to radeon_set_pcie_lanes() in rs600_pm_misc() in rs600.c.
