Title:
GRUB2 builds from Groovy, Hirsute, Impish can not boot kernel on Yoga
C630 WOS
Status in grub2 package in Ubuntu:
New
Bug description:
Hello!
After upgrade working Focal aarch64 installation on Lenovo Yoga C630
WOS (Qualcomm Snapdragon 850) I found that GRUB2 builds from Groovy,
Hirsute and Impish can not boot Linux kernel - laptop is either soft
lockup (Ctrl+Alt+Del works) or hard lockup (Ctrl+Alt+Del doesn't work)
right after "Loading device tree" message before messages from kernel
appear on the screen.
Attempts to boot with "nomodeset", "acpi=force", "earlycon=efifb"
options doesn't make any difference. On other hand rolling back GRUB2
packages back to 2.04-1ubuntu26 fixes the issue.
