Subject: [PATCH] dracut.sh: fix early microcode detection logic
|
|
|
1573a3 |
|
|
|
1573a3 |
This fixes two issues:
|
|
|
1573a3 |
|
|
|
1573a3 |
1) on non-x86 systems in non-hostonly config this would cause
|
|
|
1573a3 |
an annoying warning on every initramfs generation
|
|
|
1573a3 |
2) on non-x86 systems in hostonly config this would result in
|
|
|
1573a3 |
early microcode not getting disabled
|
|
|
1573a3 |
|
|
|
1573a3 |
Resolves: rhbz#2022414
