kernel log on boot failure
Since testing kernel 4.10 preRC, RC1 and RC2, my laptop hangs on boot at line
fb : switch to amdgpudrmfb from EVI VGA.
A few specs :
APU : AMD A10-7300 Radeon R6, 10 Compute Cores 4C+6G (from /proc/cpuinfo).
iGPU : 00:01.1 Audio device: Advanced Micro Devices, Inc. [AMD/ATI] Kaveri
HDMI/DP Audio Controller
dGPU : 01:00.0 Display controller: Advanced Micro Devices, Inc. [AMD/ATI] Topaz
XT [Radeon R7 M260/M265 / M340/M360 / M440/M445]
Xorg : 1.18.4, on Arch Linux
Boot command line : BOOT_IMAGE=/boot/vmlinuz-linux
root=UUID=76ba28b4-683c-4a39-96ef-6a1105905567 rw acpi=off (I have to use
acpi=off on 4.10-rcX to go beyonf initramfs loading)
Whatever amdgpu module's option combination I use is of no avail. These ones
(aspm=0 bapm=0 runpm=0 powerplay=1) allow me to use amdgpu on 4.9.
Attached is a kernel.log file where there is a stack trace of amdgpu module
crashing.
I can use 4.10-rc2 on my desktop with RX480 and an old Phenom II x6 CPU.
I am posting here in the hope of getting developer attention to care about this
module's crashing, on KMS seemingly. If I use nomodeset, the module gets
loaded, but obviously, there's no X session beyond.
Regards.
