Re: Linux 3.4 released

Hello,

meanwhile I tried the support of vga-switcheroo for HD-audio from your git tree
without success.

Since I'm not familiar with git I'll describe what I did:

$ git clone git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
$ cd linux
$ git reset --keep v3.4
$ git pull git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound.git
tags/hda-switcheroo

This resulted in a merge conflict for file
drivers/gpu/drm/i915/intel_ringbuffer.c which I didn't resolve since both of my
GPU are AMD radeon chips.

$ cp -p /boot/config-3.4.0 .config
$ make oldconfig
$ make
$ make modules_install

After installing kernel and system map (I don't use an initrd) , I restarted the
notebook. Before starting X, when I call the script which should mount debugfs
and switche off the discrete GPU, the system freezes.
I haven't written down all of the text on the console. It seems to be a sequence
of bugs, but I couldn't scroll back. The last stack trace begins with

... wq_worker_sleeping+0x8/0x80
... __scheduler+0x35b/0x510
... do_exit+0x542/0x830
