Unix & Linux Asked by Gilles Quenot on February 15, 2021
When I try to boot without power supply, it fails.
I have to plug the power supply to make it works.
I don’t have any debug message, because when the OS freeze, the Mint box ping, but ssh is out.
For information, my laptop is a Lenovo T495. It’s not a old model like in this answer.
And when I choose in grub the rescue mode, it works. So it’s really a software issue, not a hardware issue like @Terdon said in the other post
The solution: adding iommu
variable to grub:
GRUB_CMDLINE_LINUX_DEFAULT="iommu=soft quiet splash"
in
/etc/default/grub
