Mageia 4 on i686

Hi,

I've installed PC with a older CPU:

But now I get some Illegal instruction errors: The first time I got it was from the nouveau-driver. I cant provide the log-message since i changed to vesa and mageia seems to remove dmsg-log files every second boot-process.

But with midori and the flash player it seems to be the same:

PS: Mageia 2 was running without of problems.

hi

was this an upgrade or a fresh install?

If a fresh install did you do the md5 check before burning the iso to usb / dvd / cd?

If an upgrade was it from above disk image or an online upgrade?
If the online upgrade did you choose to download all files first or download as required?

IIRC there was file system change from M2 to M3 [ or M4 ] which caused a few headaches for upgrades.

fresh install

I didn't use a CD or an USB flash drive. I made a network installation. (I think the installer is using urpmi which checks the downloaded rpms)

[benmc]

hi

Hmmmm.
Have you, as root, run urpmi --auto-update?

just to check that you have a good mirror.

@wanne
flashplayer and webkit are using sse2 but your ancient K6-CPU is not sse2 enabled.

[wanne]

That mean The system reqirements on the websites of Adobe and Mageia are wrong and when you have an older CPU you hve to go to gentoo or something like that?

Do someone know a simple tool, that finds binarys with sse2/sse3/ssse instructions?
I tryed this, but that's realy slow and I don't think, that it's realy stable:

Code: Select all

objdump -d {} | tr "\t" "&" | grep -E "&0f (1[01234567]|2[89abcdef]|5|6|7[123456789]|c[23456]|d|e|f)" | grep -E -q "&(addpd|addsd|andnpd|andpd|cmppd|cmpsd|comisd|cvtdq2pd|cvtdq2ps|cvtpd2dq|cvtpd2pi|cvtpd2ps|cvtpi2pd|cvtps2dq|cvtps2pd|cvtsd2si|cvtsd2ss|cvtsi2sd|cvtss2sd|cvttpd2dq|cvttpd2pi|cvttps2dq|cvttsd2si|divpd|divsd|maxpd|maxsd|minpd|minsd|movapd|movhpd|movlpd|movmskpd|movsd|movupd|mulpd|mulsd|orpd|shufpd|sqrtpd|sqrtsd|subpd|subsd|ucomisd|unpckhpd|unpcklpd|xorpd|movdq2q|movdqa|movdqu|movq2dq|paddq|psubq|pmuludq|pshufhw|pshuflw|pshufd|pslldq|psrldq|punpckhqdq|punpcklqdq)"

Btw: Is it not a little bit senceless to provide 32Bit-rpms when they need sse2? There only a hand full of CPUs which support sse2 but no x86_64

We obviously cannot influence what flashplayer requires, and it's not contained in the default installation. Not sure about webkit.
Feel free to create a list of things from the default installation which require SSE2 so we can adjust the system requirements.

for the flash-issue have a look here: https://wiki.mageia.org/en/Flash_Plugin_Installation

It's almost what I've made. I just changed to chromium.

May not per default but if you change some ticks.

But for me this is not the problem. If I know the problem I know which programms/packages are affected I can recompile them. But every package is named i586 (which was introduces 1993 and is supported by almost every intel/AMD CPU which is used at the moment.) but some of them need sse2 (Which was introduced eleven years later. And there is no i586 CPU which support this.) and there is no way to find out what is what. (Even midori crash only on some websites and I cant find sse2 instructions neither in libjavascriptcoregtk-1.0 nor in midori itself but gdb says that there is at least one.) For me the rpm-sources are the key feature of Mageia. Up to now I thought: If I use the official sources, I have to care about nothing. Updates, dependencies, stable code, right architecture, linking to the right libraries... Mageia does it for me.

Feel free to create a list of things from the default installation which require SSE2 so we can adjust the system requirements.

If I find a way how I can do this in a simple way I will do this. At the moment it seems that at least the kernel-Package contains some SSE2 instructions.

Well then at least create a placeholder bug and mention the issues you already encountered there, as those seem all valid and should be fixed.
Some related ones do already exist:
