Subject: Kernel 5.14 does not boot Lenovo Thinkpad E595 (Ryzen 7 3700U)
Date: Mon, 20 Sep 2021 18:30:38 +0000
Dear maintainers,
I might be hitting the same problem, but I can see the kernel panic
message:
First a couple of lines saying:
"AMD-Vi: Completion-Wait loop timed out"
then:
"Kernel panic - not syncing: timer does't work through
Interrupt-remapped IO-APIC"
I was experiencing this also with the 5.14.0-trunk kernel and the 5.13
before from experimental.
I updated the Lenovo BIOS to the current version but the problem
persists. Also, booting with "amd_iommu=off" did not help.
Do you need more information? Unfortunately this did not make it to the
system logs.
kind regards,
Jens-Michael

Control: found -1 5.14.6-2
I have just tried installing the kernel from unstable. After reboot, the
booting process just hung at the very early stage. Nothing was printed onto
the screen, and I cannot find the logs, as it happened during booting from
initramfs.
The problem may be specific to Debian, as I tried booting openSUSE Tumbleweed
from LiveUSB with kernel 5.14.5, and it worked fine.
I am using Lenovo Thinkpad E495 with AMD Ryzen 5 3500U CPU.

Is it still reproducible when adding 'mem_encrypt=off' to the kernel command

Thanks for testing, Alexander!
Jens-Michael, Gert, how does your system behave when

With 'mem_encrypt=off' the kernel (5.14.6-2) boots fine.

With 'mem_encrypt=off' the kernel boots fine, thanks for the pointer.
@Bastian: I'm not sure I understand why you downgraded the bug to
important (I could have understood serious, grave).
When the package is installed as is, one can't boot from this kernel,
so the package should not got into testing as is, and for that reason
the severity should be "serious" at least (But I don't want to go into
a severity fight, so I don't add a control line to change this).
Best,
Gert

Subject: Hit with linux-image-5.14.0-1-amd64 on Ryzen 5 3500U
Date: Tue, 28 Sep 2021 19:09:32 +0100
I've hit this issue with the linux-image-5.14.0-1-amd64 (5.14.6-2) that
has made its way to testing this week; symptom is grub never shows
anything after the loading the initrd message. earlycon=efifb and
earlyprintk=efi didn't give any extra output. mem_encrypt=off resulted
in a successful boot.
Hardware is a Ryzen 3 3500U laptop. It seems like this is a potential
interaction between the memory encryption and amdgpu?
