[Solved] General Protection faults on package installation intel-ucode

zenolijo · 2016-01-08 13:45:54

I have seen a few packages breaking upon installation, and all of them do it in post-installation scripts when installing packages.
After some googling i found these two links that propose the same issue and has a solution link1 link2. However, they simply solve their issues by installing and configuring intel-ucode, and even though i have that fully working i still get segmentation faults.

The strangest part about this is that according to the ArchWiki, you shouldn't need the intel-ucode if your processor is not listed here, and mine isn't (i5 6600k). And according to the ArchWiki again, the dmesg output from down below proves this.

Is this something that should be reported upstream to intel, or am i supposed to do? I see no way to fix this and would love some input either on what I've done wrong, if I'm on the wrong track or if this actually is a microcode bug.

Proof that it's a General Protection Fault?

dmesg | tail -n 1

[   60.495484] traps: vlc-cache-gen[3388] general protection ip:7ff15acbd7e0 sp:7ffcbd93e628 error:0 in libpthread-2.22.so[7ff15acab000+18000]

Proof that Intel ucode is being properly loaded

dmesg | grep microcode | xclip -i -selection clipboard

[    0.313691] microcode: CPU0 sig=0x506e3, pf=0x2, revision=0x39
[    0.313698] microcode: CPU1 sig=0x506e3, pf=0x2, revision=0x39

[    0.313757] microcode: Microcode Update Driver: v2.00 <tigran@aivazian.fsnet.co.uk>, Peter Oruba

Last time i updated my BIOS was in late november, if that makes any difference

sudo dmidecode | grep "Release Date"

	Release Date: 11/19/2015

Proof that my kernel is loaded with initrd=/intel-ucode.img

dmesg | grep ucode

[    0.000000] Command line: root=/dev/sdc2 rw initrd=/intel-ucode.img initrd=/initramfs-linux.img
[    0.000000] Kernel command line: root=/dev/sdc2 rw initrd=/intel-ucode.img initrd=/initramfs-linux.img

My genefi.sh script that generates Arch's bootentry with efibootmgr

cat /boot/genefi.sh

#!/bin/bash
# Remove old entry at 0000
efibootmgr -b 0000 -B
# Create new entry at 0000
efibootmgr -b 0000 -d /dev/sdc -p 1 -c -L "Arch Linux" -l /vmlinuz-linux -u "root=/dev/sdc2 rw initrd=/intel-ucode.img initrd=/initramfs-linux.img"

The packages that get segfaults on my system: texlive-core, gtk2, gtk3, vlc, gdk-puxbuf2

All these commands that segfaults can be run successfully if run inside valgrind, for example if i want to fix vlc i run "sudo valgrind /usr/lib/vlc/vlc-cache-gen -f /usr/lib/vlc/plugins"

cat /var/log/pacman.log | grep "Segmentation fault"

Note that the driver slated to fix this is in testing and there apparently was a new microcode release (not yet in the repos) both of which might help.

Interesting find, thanks. I do have a nvidia card.

I've been having this issue since i installed Arch on this computer back in October, I guess that i can wait for the new microcode to go into the main repo.

I finally had time to, still kind of confused.

As seen here, it updated

pacman -Qs intel-ucode

local/intel-ucode 20151106-1
    Microcode update files for Intel CPUs

I see that the .img file was changed at the update

ll /boot/intel-ucode.img

-rwxr-xr-x 1 root root 692736 Jan 10 19:42 /boot/intel-ucode.img*

However, still seems like it's the same intel-ucode version?

dmesg | grep microcode

[    0.316239] microcode: CPU0 sig=0x506e3, pf=0x2, revision=0x39
[    0.316249] microcode: CPU1 sig=0x506e3, pf=0x2, revision=0x39

My processor is not listed on the intel download page for the new microcode update either, so i guess that it just skips it?

Looks like it. As said rebuilding glibc without lock elision definitely helped here, and the current nvidia driver in testing is supposed to fix this although I've heard it can lead to complications with QT5 applications (EDIT: should be fixed), so I haven't tested it yet

Didn't want to enable [testing], so i checked if any of nvidias dependencies had updated which wasn't the case.

Downloaded these nvidia packages from testing, restarted, and voila! Everything seems to work

Thanks alot for the help everyone, marking this as solved.
