cut_here KERNEL PANIC
Trying to enable AMD R5-M230 Southern Islands (SI) laptop discrete GPU - by
using the latest stable 4.11.5 Linux Kernel and the latest Mesa 17.1.2 .
Already blacklisted radeon kernel module. However I can not boot with AMDGPU
after it is giving me these errors:
[drm] amdgpu kernel modesetting enabled.
[drm] initializing kernel modesetting (HAINAN 0x1002:0x6665 0x0000:0x0000
0x00).
[drm] register mmio base: 0xF0300000
[drm] register mmio size: 262144
amdgpu 0000:04:00.0: Invalid PCI ROM header signature: expecting 0xaa55, got
0x0000
[drm] vbios mem is null or mem size is wrong
amdgpu 0000:04:00.0: Invalid PCI ROM header signature: expecting 0xaa55, got
0x0000
[drm] vbios mem is null or mem size is wrong
[drm:amdgpu_get_bios [amdgpu]] *ERROR* Unable to locate a BIOS ROM
amdgpu 0000:04:00.0: Fatal error during GPU init
[drm] amdgpu: finishing device.
<=== KERNEL PANIC, "cut here" is inside the attachments
This is AMDGPU blocker issue, because I could boot only if I add "nomodeset" to
kernel parameters</pre>
