Subject: [BUG] 2.6.30-rc4 hid bluetooth not working

Hi all!

My bluetooth keyboard is not working any more in rc4, but was working in rc3.

Here is the dmesg output, triggered by the first key press on the keyboard, fortunately, this
is 100% reproductible (once per boot).

Attached my .config and the full dmesg output from boot, just in case.

Best regards

Marc
