Subject: i82875p_edac: BAR 0 collision
Date: Fri, 7 Nov 2008 13:43:55 +0200	[thread overview]
Message-ID: <20081107114355.GA31730@piipiip.net> (raw)

When I try to load i82875p_edac module on ASUS P4C800 Deluxe in 2.6.26
or 2.6.27 it fails due to BAR 0 collision. On 2.6.25 the
i82875p_edac works just fine.

Should i82875p_setup_overfl_dev() do some additional work to fix the
missing resource of the hidden overflow device?

When I try load i82875p_edac module on 2.6.27 I get

  # modprobe i82875p_edac
  FATAL: Error inserting i82875p_edac
  (/lib/modules/2.6.27.4/kernel/drivers/edac/i82875p_edac.ko): No such device

And dmesg shows (from 2.6.27.4):

  EDAC MC: Ver: 2.1.0 Oct 30 2008
  EDAC DEBUG: edac_pci_dev_parity_clear()

On 2.6.25.19 loading i82875p_edac works just fine and dmesg shows:

  EDAC MC: Ver: 2.1.0 Nov  4 2008
  EDAC i82875p: i82875p init one
