Bug ID: 111685
Summary: [Polaris 30] [Bisected] Kernel BUG during boot when
amdgpu.dpm=0
Product: DRI
Version: DRI git
Hardware: x86-64 (AMD64)
OS: Linux (All)
Status: NEW
Severity: normal
Priority: not set
Component: DRM/AMDgpu
Assignee: dri-devel@lists.freedesktop.org

Bisect log
To reproduce, pass the parameter amdgpu.dpm=0 to a kernel v5.2 or higher. The
kernel will hang at boot. v5.1 boots correctly.
I have bisected the kernel between v5.1 and v5.2, the bisect log is attached
below.
The last three lines from the log are as follow, the full log is attached
below:
kernel: BUG: unable to handle page fault for address: ffff91fe41bdf5f8
kernel: #PF: supervisor read access in kernel mode
kernel: #PF: error_code(0x0000) - not-present page
