Comment 1 Thomas Backlund 2017-05-26 23:16:09 CEST
Is there enough free space in /boot ?

is there an initrd-4.4.68-desktop-1.mga5.img in /boot ?

This is the grub menu.lst having all the available kernels. I can boot into 4.4.65 and not into 4.4.68

I asked for /var/log/dmesg, not the output of dmesg.

The difference is that /var/log/dmesg contains info from hardware bootup, whereas dmesg will only show whats currently in dmesg buffer

I added the output of lspcidrake -v and dmesg as requested and also added the output of blkid and lsblk in case that would help.
Thank you

Hi Leon,


Thank you for having taken the needed time to report this issue and supply all requested information!

This bug was filed against Mageia 5. Did it get fixed? If so, please change its status to RESOLVED - FIXED.

If it didn't, then we regret that we weren't able to fix it in Mageia 5. Mageia 5 has officially reached its End of Life on December 31st, 2017 https://blog.mageia.org/en/2017/11/07/mageia-5-eol-postponed/
It continued to get limited extended support since then, but that support has now ended, too.
As a result we are closing this bug report as OLD.

If you still see this issue in a newer Mageia version, then please reopen this report and say so.
