Description Guo-Rong Koh 2007-02-05 17:00:01 UTC

Most recent kernel where this bug did *NOT* occur: Unknown, never tried
Distribution: Gentoo Linux
Hardware Environment: Acer Ferrari 4005WLMi
Software Environment: Console, no X, acpid running
Problem Description:

Hotplugging an Acer Ferrari 4005 into its dock results in the kernel issuing a BUG message.
Kernel seems to continue OK after this. Additional USB controllers in the dock station also seem 
to be hotplugged correctly (and work).

Steps to reproduce:

Configure ACPI hotplug into kernel
Configure SHPC into kernel
Configure PCI and PCIE hotplug

Boot notebook without dock attached.
Attach dock, get this in the kernel output:

Comment 1 Len Brown 2007-02-05 20:17:50 UTC

same if you boot with "pci=nommconf"?

Comment 2 Guo-Rong Koh 2007-02-05 22:38:29 UTC

Same with 'pci=nommconf'.
The notebook may be PCIE (not PCI) hotplug if that makes any difference?

Comment 3 Kristen 2007-11-27 10:02:31 UTC

Hi, can you let us know if you are still having a problem with the dock driver and the most recent kernel version?  Thanks.

Comment 4 Guo-Rong Koh 2007-11-27 14:59:02 UTC

Hi, unfortunately I am no longer in possession of the laptop to test it.
I'll be happy to mark it unreproducible.
Thanks.
