 Posted: Mon Jul 14, 2014 9:08 am Post subject: Firefox crashes Xorg. Illegal instructions [SOLVED] |
 |
|
First of all, I reckon there is a similar thread (https://forums.gentoo.org/viewtopic-t-995292.html). However, some things are different (he claims the problem happens after opening various tabs, I have problems with displaying media and tabs work fine), searching in google I found the same error with very different causes (and those solutions didn't work for me, so there might be various bugs? In any case, I am more than happy is this threads need to be merged
The consequences are the same tough: X crashes and I am kicked to a console. Usually after trying to pause a video (both using flash or html5), after such video finishes or simply by going to a site with tons of pictures (like google images)
As this crashes firefox I can't see if there is any debug message. However, I get a crash log on my X server http://bpaste.net/show/461692/.
I tried some heavy web browsers, like chromium (segfault, illegal instruction), chrome (segfault, illegal instruction), qupzilla (segfault, illegal instruction). I can't check why they fail as they take just more than the whole night to compile on my system, and I don't have the patience. I am left with Firefox only (dillo and links won't crash xorg, but they can't play videos either. Images work fine, but no animated gifs).
The crash log doesn't clear me much. Some kind of memory mess?
my graphic card is an ATI RV515/M52 (lspci also says "Mobility Radeon X1300").
I am inclined to blame firefox because games and other software works flawlessly, only firefox is being rude towards me
* I also tried revdep-update, but every single time I do it, it recompiles GCC, (that is another problem to fix), so I avoid it like the plague. Both problems mention directfb somewhere (directfb is recompiled with revdep-update too, and I can see an error thrown by the same library on xorg). Maybe it is related? I can't remove directfb as I do a lot of work from the terminal...

| "illegal instruction" errors in most cases (barring rare compiler bugs) usually are user errors. - in case of Gentoo, most likely reason is setting your C{XX}FLAGS wrong. |

Agreed, can you please post:
- your /etc/portage/make.conf
- the output of emerge --info
- one of the stanzas of /proc/cpuinfo (you will see it is repeated per core, we only need the info once)
As Voidmage says it is probable that there is an error in your configuration somewhere, and that should give us a good start as to what is wrong.

Thanks for the reply. I actually did read that at least chromium is very picky with its optimization flags. There is my configuration files.
make.conf
CFLAGS="-march=core2 -O2 -fomit-frame-pointer -pipe"
CXXFLAGS="-march=core2 -O2 -fomit-frame-pointer -pipe"
MAKEOPTS="-j3"
LINGUAS="en_GB"
VIDEO_CARDS="radeon"
INPUT_DEVICES="synaptics evdev"
USE="midi timidity multicore mmx sse sse2 sse3 sse4_1 ssse3 gif ccdb xmpp \
musepack xmmp cue aalib libcaca directfb gpm fbcon offensive \
alsa savedconfig xinerama"

Also, note that recent versions of gcc support the -march=native option, which will autodetect the appropriate optimisation settings to use without you having to trying to match your ark.intel.com entry to the available options in the manpage (which is an artform in itself sometimes;)).
(although a minor health warning is that this option is entirely incompatible with distcc, as it causes each build host to optimise for itself)

I was so sure I had a Core2!
Well, in any case I'll need to also recompile my kernel plus all the distribution again, so it will be some busy couple of days. I would love to use distcc, but my emergency laptop is X86_64 and I know there can be problems cross compiling...
Thank you for the reply. I am going to start this night and post results after I finish |

Changed the arch, recompiled the whole system with emerge -e @world and now everything works like a charm. Thank you!  |

vladimir1986 ... eccerr0r is correct in that its a "core duo" (and so an "enhanced pentium-m") and not a "core2". With -march=core2 you will enable avx, sse4.x, and other optimisations that the processor doesn't support ... -march=native will set/detect "-march=pentium-m" and disable those optimisations.
You can also remove the sse3 sse4_1 useflags ... it only supports up to sse2.
best ... khay |

Done, and thank you for the warning!
Right now I am on my menuconfig, as I did choose core2 when I compiled my kernel. I assume that even if it just works, It will be good if I change it. You say that my CPU is a pentium-m (as you can see, I am quite illiterate about CPUS). I assume that I shall change it to Pentium4-m ?
The scarce info on the kernel tells that Pentium-m is used for notebooks, and later I have the option to choose Pentium4-M. At the same time, an old 2007-2008 post said that he used Pentium 4 on his Thinkpad T60 (is my laptop, and I am assuming that the config file would be slightly different back then) as the cpu is based on Pentium 4. I know the T60 shipped with two different CPUs, but both the old post an my laptop are using a family 6... |

Your cpu is a "core duo" (which is based on pentium-m but has "extended" features). Anyhow, you should probably choose CONFIG_MNATIVE=y this way the compiler will work out what the cpu is and what features it supports.

Yeah, the 'm' stands or "mobile", the core duo just followed on after so had much the same design.
