Description Takashi Iwai 2023-11-10 15:07:39 UTC

When a new kernel (6.6 or later) is installed on Leap 15.5 system, dracut doesn't put the CPU microcode any longer, spewing
  Disabling early microcode, because kernel does not support it. CONFIG_MICROCODE_[AMD|INTEL]!=y

The kernel dropped those kconfigs but has only CONFIG_MICROCODE=y since 6.6.

Please take the upstream dracut fix for dropping this check to SLE15-SP5 / Leap 15.5 dracut package.

Hi Takashi, the fix was already backported to Factory, but not to any SLE code stream. Do you need it only for Leap 15.5?

Comment 2 Takashi Iwai 2023-11-10 15:20:10 UTC

I personally am fine with only Leap 15.5 :)  Of course, it should be fixed for SLE15-SP6, too, if any.

Leap 15.4 will be discontinued in a few weeks, so I guess we can skip it.

Note that the use of new kernel from OBS Kernel:stable:Backport is popular among many Leap users, and the problem appeared only recently.

Better safe than sorry :)

Fix backported to SP4/5/6, so it should be available in upcoming maintenance updates for SP4/5 and in SP6 GA.

Closing.
