Comment 16 for bug 1070770

To use multirom, I need to install kernel_kexec_42.zip as described here
http://rootingandroid.net/how-to-install-multiple-roms-and-ubuntu-on-a-nexus-7/
(I found out when doing an apt-get upgrade that it wouldn't boot anymore, after the kernel was upgraded)
Then I'm not seeing that there is a bluetooth device. lsusb doesn't find one, hcitool scan says "No such device" and so on. Does there need to be an hci attach somewhere, if this is a serial-attached BT chip? Or is it just a missing driver in that kernel? If so, could someone provide an updated kernel image that has the bluetooth fixes and also the kexec-hardboot patch for multirom?
