I think this is more likely an ACPI or dock driver problem than a
PCI problem, but I know very little about docks.

I think it's different from the problem you found on the mailing
list, so can you please open a kernel bugzilla report at

  http://bugzilla.kernel.org/enter_bug.cgi?product=ACPI

and attach your dmesg, lspci, and acpidump?  Please respond to this
thread with the new bugzilla URL.

Thanks,
