Subject: fixing "pci=use_crs"
Date: Wed, 16 Sep 2009 17:15:23 -0600	[thread overview]
Message-ID: <200909161715.24376.bjorn.helgaas@hp.com> (raw)

The user currently has to boot with "pci=use_crs" to make
hot-add work on some machines.  I think this is a poor
user experience, and I'd like to figure out a better solution.

We tried making "pci=use_crs" the default, which didn't work
because it broke machines like Larry's.  I'd like to look
at that machine in more detail and figure out what it's doing.

Larry, would you mind collecting the output of:

  # dmesg
  # cat /proc/iomem
  # lspci -vv
  # cd /sys/devices/; grep . pnp*/*/{id,resources}

and attaching them here:

    http://bugzilla.kernel.org/show_bug.cgi?id=14183

Thanks,
  Bjorn
