Len, This small patchset fixes a regression that causes OOPSes on the ACPI core during bay or dock operations when thinkpad-acpi is loaded and allowed to bind to the dock or bay nodes. This is not a very common configuration, which explains why I only heard of it very recently. Most users prefer the generic ACPI dock/bay driver for good reasons (and I am one of them :P ), and most of the time, thinkpad-acpi loads later so it doesn't get to bind to the bay node. Please send at least the first patch (but preferably both) to Linus to fix the issue in mainline. If it is too late for the second patch, I will resubmit it for the next merge window. The stable team should get the first patch, which makes sure the broken features are normally disabled in a minimalistic way. Thank you. -- "One disk to rule them all, One disk to find them.
