Description Markus Robert Keßler 2019-08-14 19:20:13 CEST
Description of problem:

An update was started today, installing

    kernel-server-4.18.20-1.mga6-1-1.mga6.i586

After rebooting, grub appears and after that there is nothing but a black screen, not even kernel messages.
Though, the machine does not crash completely, since numlock still works.

Tested on FSC Lifebook 8310 with intel graphics, hence kernel module i915.

B.t.w.: After updating MGA7 as virtual machine on a MGA6 hardware box this also occurred. So, it seems that MGA7 is also affected.

Temporary workaround: Select previous kernel in grub and use this one.

Version-Release number of selected component (if applicable):
kernel 4.18.20

How reproducible:
Always


Steps to Reproduce:
1. Do the update to mentioned kernel
2. Reboot as demanded
3.

@Mathus: can you please say what is the 'previous' kernel that works.
Under Mageia 6, is this real hardware?
Please be more specific about your Intel graphics hardware.

> Temporary workaround: Select previous kernel in grub and use this one
This does suggest a kernel problem, so assigning it appropriately.

Previous kernel was / is 4.14.137-server-1.mga6.
This is real hardware.

After that, I uninstalled all *kernel*4.18.20* stuff, ran update-grub and the machine runs again flawlessly.
