Bug#878221: linux-image-4.9.0-4-amd64: Screen flickers randomly with Radeon R9 270X since upgrade from 4.9.0-3 to 4.9.0-4

2018-01-23 Thread Robin Gareus 
The recent backport kernel does *not* have this issue. All is fine with

 4.14.0-0.bpo.3-amd64 #1 SMP Debian 4.14.13-1~bpo9+1 (2018-01-14)

This is on a Thinkpad X250 with 00:02.0 VGA compatible controller: Intel
Corporation HD Graphics 5500 (rev 09)

4.9.0-4-amd64 and 4.9.0-5-amd64 on the same box do cause screen flickering.



Chances are that the issue was introduced by the update to upstream
4.9.46. There are a handful of "drm/i915" changes:

https://anonscm.debian.org/git/kernel/linux.git/commit/?h=debian/4.9.65-3%2bdeb9u2=17811b5a4b11b32307baca3b88067398a1168cfb

"Workaround VLV/CHV DSI scanline counter hardware fail" sounds
suspicious, but that's just a guess.

Bug#887389: Bug solved

2018-01-23 Thread Arnaud Courtès 
On Buster (testing at the moment), with the last 4.14 linux kernel 
image, speedstep works again correctly :)


We can say the bug is solved.

Okay.  I'll do that.

There's an upstream change in cfg80211 that enables direct-loading of
wireless rules, which requires public key crypto in the kernel.  There
doesn't appear to be any option to disable that mode, even though we
don't need it because crda still works.  Maybe you could disable
wireless networking completely?

Some options that could possibly be changed from y to m:

- I2C, I2C_CHARDEV, I2C_MV64XXX.  initramfs-tools should include I2C
drivers to the initramfs if needed, but I'm not certain.

- MTD, MTD_CMDLINE_PARTS, etc.  But I'm pretty sure this will break
some systems unless initramfs-tools is updated to include and load the
cmdlinepart module.

- RTC_DRV_MV (and disable RTC_HCTOSYS).  There's a udev rule that
should load the system clock from the first RTC if its driver is a
module.

- SPI_ORION.  initramfs-tools should include this in the initramfs if
needed, but I'm not certain.

Some options that could possibly be disabled:

- AUDIT.  This is quite a niche feature.

Also try comparing the complete configs over time and looking for
symbols newly set to y.

Ben.

Yes, let's change to SLUB.  I think SLUB_DEBUG and
SLAB_FREELIST_HARDENED should be enabled, except on armel/marvell.

Bug#886746: Bug exists in vanilla kernel 4.9.65

2018-01-23 Thread John Hughes 
I've compiled a vanilla kernel 4.9.65 (from 
git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git) 
and the bug is present.  Vanilla kernel 4.9.30 works.


I'll roll up my sleeves and start bisecting.

Bug#888106: initramfs-tools: mkinitramfs should fail when ldd fails in copy_exec

2018-01-23 Thread Andrew Shadura 
Package: initramfs-tools
Version: 0.130
Severity: minor

Dear Maintainer,

We're working on a minimalist build of a Debian derivative which doesn't
include bash, and we ran into an situation in which due to a human error
the system didn't have a working ldd. This wasn't detected during an
image build process as mkinitramfs happily ignored ldd not working
(while being present and being an executable), and proceeded creating
a broken initramfs. In hook-functions, copy_exec does the following:

# Copy the dependant libraries
for x in $(ldd "${src}" 2>/dev/null | sed -e …)
do
done

The return code of ldd is not handled at all. Should ldd fail for any
reason, this failure will be ignored.

I tried to write a patch, but I couldn't come up with an elegant
solution which would cover cases other than just a wrong hashbang in
ldd :)

Maybe something like https://www.spinics.net/lists/dash/msg00165.html
can be used, but it's up to you to introduce hacks like that into the
code.

Thanks in advance.
