Package: src:linux
Version: 5.14.6-2
Severity: critical
Justification: breaks the whole system
Dear Maintainer,
* What led up to the situation?
Booting an AMD Raven Bridge computer with this kernel renders the system
unusable because the amdgpu driver
cannot initialize. This happens because the kernel config enables secure memory
encryption (SME) which
is not compatible with RAVEN [1]. In this case, the kernel will contain:
amdgpu: SME is not compatible with RAVEN
* What exactly did you do (or not do) that was effective (or
ineffective)?
Disabling SME is the only option, passing mem_encrypt=off to the kernel solves
the problem
Since disabling SME on all systems is clearly overkill, I think the best option
would be for the GRUB
scripts to probe for Raven Bridge and add "mem_encrypt=off". Based on [1], this
should probably be done
by looking at the PCI devices.
