| |
Hi,
When backporting some btrfs specific patches to all LTS kernels, I found v4.14.290 kernel unable to boot as a KVM guest with edk2-ovmf (edk2-ovmf: 202205, qemu 7.0.0, libvirt 1:8.6.0).
While all other LTS/stable branches (4.19.x, 5.4.x, 5.10.x, 5.15.x, 5.18.x, 5.19.x) can boot without a hipccup.
I tried the following configs, but none of them can even provide an early output:
- CONFIG_X86_VERBOSE_BOOTUP - CONFIG_EARLY_PRINTK - CONFIG_EARLY_PRINTK_EFI
Is this a known bug or something new?
Thanks, Qu
