Lenovo A740 gave up waiting for root device with kernels >= 4.3

From: Kevin Brubeck Unhammer

[1.] One line summary of the problem:
Lenovo A740 does not boot with kernel >= 4.3, "gave up waiting for root device"

[2.] Full description of the problem/report:

I have a Lenovo A740 (running Xubuntu 16.04) which, with kernel
versions >= 4.3, gives this on trying to boot:

Begin: Waiting for root file system ... Begin: Running
/scripts/local-block ... done.
Begin: Running /scripts/local-block ... done.
Begin: Running /scripts/local-block ... done.
[â]
done.
Gave up waiting for root device.

and drops me into an (initramfs) shell, where my keyboard is
unresponsive. Images of the screen are at:

https://launchpadlibrarian.net/255781692/drop.jpg

It boots fine with earlier kernels, e.g. 4.2.0. After trying various
packages from http://kernel.ubuntu.com/~kernel-ppa/mainline/ it seems
anything 4.3 or higher gives the issue, while
linux-image-4.2.8-040208-generic_4.2.8-040208.201512150620_amd64.deb is
the highest version that I can get to boot.

I've filed an Ubuntu bug report at
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1574178 and was
asked to move the issue upstream.

[3.] Keywords (i.e., modules, networking, kernel):

filesystem maybe?

[4.] Kernel version (from /proc/version):

linux-image-4.3.0-040300-generic_4.3.0-040300.201511020949_amd64.deb
or higher

[5.] Output of Oops.. message (if applicable) with symbolic information
resolved (see Documentation/oops-tracing.txt)
[6.] A small shell script or example program which triggers the
problem (if possible)
[7.] Environment
[7.1.] Software (add the output of the ver_linux script here)

I guess scripts/ver_linux isn't of much use since I can't boot 4.3 or
higher anyway, but here it is just in case:


$ sh scripts/ver_linux
If some fields are empty or look unusual you may have an old version.
Compare to the current minimal requirements in Documentation/Changes.

[7.6.] SCSI information (from /proc/scsi/scsi)

(from running 4.2)

Attached devices:
Host: scsi0 Channel: 00 Id: 00 Lun: 00
Vendor: ATA Model: ST1000LM014-1EJ1 Rev: LIV6
Type: Direct-Access ANSI SCSI revision: 05

[7.7.] Other information that might be relevant to the problem
(please look in /proc and include all information that you
think to be relevant):

Might not be relevant, but: The system also does not power off (nor
restart) on shutdown, I need to physically press the power key, and it
never has done with any of the kernels I've tried. It does restart with
ctrl+alt+delete from grub though. Reported at
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1463422

Lenovo's site has a BIOS update for Broadwell systems, but there is
nothing listed for Haswell.

[X.] Other notes, patches, fixes, workarounds:

I unfortunately know of no workarounds other than sticking with 4.2.


What can I do to help get this regression fixed?
