[Bug 1268880] Re: unable to toggle microphone mute on T410 / unable to unload thinkpad_acpi module
I'd like to perform a bisect to figure out what commit caused this
regression. We need to identify the earliest kernel where the issue
started happening as well as the latest kernel that did not have this
issue.
Can you test the following kernels and report back? We are looking for
the first kernel version that exhibits this bug:
v3.12 final: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.12-trusty/
If v3.12 final does not exhibit the bug, we should move on to testing some of the v3.13 release candidates.
v3.13-rc3: http://kernel.ubuntu.com/~kernel-
ppa/mainline/v3.13-rc3-trusty/
If v3.13-rc3 does not exhibit the bug then test v3.13-rc6:
v3.13-rc6: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.13-rc6-trusty/
If v3.13-rc3 does exhibit the bug then test v3.13-rc2:
v3.13-rc2: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.13-rc2-trusty
You don't have to test every kernel, just up until the kernel that first
has this bug.
Thanks in advance!

Title:
unable to toggle microphone mute on T410 / unable to unload
thinkpad_acpi module
Status in “linux” package in Ubuntu:
Confirmed
Bug description:
I recently pressed the physical microphone mute button on my Lenovo
T410. However, I am now unable to unmute it. The orange light next to
the mic mute button comes on when the kernel boots, but pressing it
has no effect.
Possibly related to this, I am now unable to unload the thinkpad_acpi
kernel module (required to run the fan in disengaged mode to work
around the long-standing bug 751689) as it seems to be permanently
hooked into the sound drivers:
$ sudo modprobe -r thinkpad_acpi
modprobe: FATAL: Module thinkpad_acpi is in use.
$ sudo lsmod|grep thinkpad_acpi
