Description peter lawford 2018-03-02 00:24:09 CET
Description of problem:
it's impossible to open firefox and thunderbird-52.6.0-1.mga6 under kernel-(desktop, server)-4.14.20-1: here below the return of the commands:

[alain4@mag6 ~]$ firefox
Instruction non permise (core dumped)
[alain4@mag6 ~]$ thunderbird
Instruction non permise (core dumped)

with kernel-(desktop, server)-4.14.18-1, these commands get no return, they simply work

then with kernel 4.14.20-1, these main applications don't work

firefox starts and runs fine inside an mga6 x86-64 vm here with kernel 4.14.20 . Does the problem in a new mageia user account?

Do you mean that the problem does not happen in a new user? Can you try using strace?

I have old mga6 system updated with latest rpms and both the firefox and thunderbird opens ok for me. Maybe some other file is corrupted in your system.

Does it help if you first try to rename the .thunderbird dir which contains the mail settings temporarily to something else and then start the thunderbird?

Given the problem (illegal instruction), this is probably related to specific CPUs. Can you attach /proc/cpuinfo file?

The strange part is that I would not expect the kernel to cause different userspace code to run. Are you using the same video drivers with the different kernels?

Normally I'd agree with prerjan, but nowdays...

It can be a fallout of the specte/meltdown fixes as there are changes all over cpu specific codepaths

Comment 7 peter lawford 2018-03-04 16:53:36 CET
solved!
I have 2 mageia6 systems: the main one comes from updating mageia5, and the second one is a duplicate of the main one on another device (say a LVM based on a level5 mdadm-raid volume) using dump/restore and dracut through chroot, and I test the updates on the copy, and if everything is OK, I update to the main one.
I suppose the copy was corrupted, due to bad dracut configuration, I've removed it and duplicate again (with changes on dracut) and now this bug no longer exists.
Unfortunately, after updating, others bugs appeared, as update includes more than 71 packages, I can't experiment each one separately, no time for that
the main new bug is that is seemed that after updating, mounting a lvm partition based on a level6 mdadm-raid volume freezes the system.
I have found numerous others dysfunctions, but posting them would need too much time, I can't afford
I think I'll soon migrate to kubuntu or mint
really sorry 
I'm about to post the new bug

I'm glad it no longer exists. I understand this issue wasn't a bug.

Thanks for all the feedback!

As the reporter of this bug, you should have been able to close it yourself ;-)
