Bug#855684: linux-image-4.9.0-1-amd64: Upgraded from 4.8+77 cannot shutdown without sysrq-sub

2017-02-20 Thread Joel Fenwick
Package: src:linux
Version: 4.9.6-3
Severity: normal

Dear Maintainer,

   * What led up to the situation?
Upgraded linux-image-amd64 to above version.
Sound no longer works.
Attempts to shutdown/reboot machine via gui menus lock.
Logging in on console and running reboot as root also locks.

sysrq-s,u,b 
succeeds in rebooting machine.

   * What exactly did you do (or not do) that was effective (or
 ineffective)?

dpkg to reinstall older kernel (4.8+77)

selecting 4.8 in grub:
  sound and rebooting capabilities work with this kernel.

selecting 4.9 in grub:
  reproduces symptoms.

booting (4.9) without usb sound device connected:
  sound and rebooting work fine.

Thanks
Joel Fenwick

Did you just reboot or go through a cold start? That might make a difference.

Bug#855183: linux-image-4.9.0-0.bpo.1-amd64: modprobe intel_rapl_perf stay in uninterruptible sleep

2017-02-20 Thread Miloslav Hůla

Dne 17.02.2017 v 11:47 Thomas Gleixner napsal(a):

What's really confusing is this information from the bug report:

" When I changed:

  Power technology:
  - from Energy Efficient
  - to Custom

  Energy Performance BIAS Setting:
  - from Balanced Performance
  - to Performance

  problem disappeared. systemd-udevd starts normally, module can be
  normally rmmod/insmod'ed now, load is 0.07."

Miloslav: Is there any chance you can try a 4.10-rc8 kernel on that
machine?


I compiled 4.10-rc8 kernel with a stock 
'/boot/config-4.9.0-0.bpo.1-amd64' config from Debian Jessie backports. 
Then I reverted BIOS settings to previous state and rebooted the server. 
Kernel and all modules loaded normally, rmmod/insmod intel_rapl_perf 
passed normally.


Then, without any BIOS change, I rebooted with stock 4.9.0-0.bpo.1-amd64 
and suprisingly, everything works, I cannot reproduce it.


My knowledge on the field of BIOS are shallow. I don't know what I can 
do to reproduce the bug now.

Bug#855646: linux-image-4.9.0-1-686-pae: [i915] kernel oops on Dell D430

2017-02-20 Thread Martin-Éric Racine
Package: src:linux
Version: 4.9.6-3
Severity: important

The DRM driver for i915 hardware oopses in a systematic way during bootup on 
this Dell D430 using kernel 4.9 from testing/frozen.

Booting with kernel 3.16 from stable/updates doesn't produce these symptoms.

You mean, define additional pinmux nodes and override the pinctrl-0
property of &sata?  More like this:

Then I believe it would be more explicit to have separate pin muxing

That is precisely what I intended.  20-23 are used by the second
Ethernet port.  The old board code doesn't assign 4 or 5 at all.

Bug#855596: Compile with CONFIG_GDB_SCRIPTS

2017-02-20 Thread Vincent Bernat
Package: src:linux
Version: 4.9.10-1
Severity: wishlist

-BEGIN PGP SIGNED MESSAGE-
Hash: SHA256

Hey!

When debugging a kernel problem, it is quite useful to get
vmlinux-gdb.py. This can be compiled with CONFIG_GDB_SCRIPTS and could
be included with the dbgsym package (or with kbuild?).

Thanks!

Bug#855017: [PATCH] ARM: dts: kirkwood: Fix SATA pinmux-ing for TS419

2017-02-20 Thread Thomas Petazzoni
Hello,

Adding in Cc all the maintainers of the Kirkwood platforms.

On Sat, 18 Feb 2017 00:32:51 +, Ben Hutchings wrote:

This is not only muxing mpp15 as sata0 and mpp16 as sata1, but also
removes the muxing of sata0/sata1 pins described in kirkwood-6282.dtsi:

pmx_sata0: pmx-sata0 {
marvell,pins = "mpp5", "mpp21", "mpp23";
marvell,function = "sata0";
};
pmx_sata1: pmx-sata1 {
marvell,pins = "mpp4", "mpp20", "mpp22";
marvell,function = "sata1";
};

So it means that MPP 4, 5, 20, 21, 22 and 23 will no longer be muxed as
sata0/sata1. Is this really what you want?

Best regards,

Thomas

Bug#852698: linux-image-4.9.0-1-amd64: nouveau seems to hang programs like lspci and Xorg

2017-02-20 Thread Bernhard Ehlers
Just tested with 4.9.10-1 from unstable, with that kernel I have no issues 
starting Xorg on my PC with a nouveau graphics card.


Bug#854353: Reporoduced on ThinkPad X220

2017-02-20 Thread Ivan Krylov
After booting linux-image-4.9.0-0.bpo.1-amd64 from jessie-backports,
wireless interface stops working within minutes after system boot.
rmmod/modprobe helps to squeeze some more and yields a warning:
