Hi, I have a laptop with A10-9600 cpu/GPU, the GPU is a R5 series. I have the last kernel (4.12) but sometime at startup the screen crashes, I just get a Rainbow screen of death, laptop not responding and I have to reboot.
Please attach your xorg log and full dmesg output.
Created attachment 134893 [details] Dmesg working This dmesg is the working after 3 reboots.
Created attachment 134895 [details] Screenshot of bug I attached a screenshot of bug
Created attachment 134896 [details] Some logs Attached a zip file containing some logs and xorg logs. Let me know if you need something else. Do I need to upgrade xorg? My kernel is 4.13.2
Ok, I found a hint: the bug appears when I turn on the laptop without the power cable. So if I turn on the laptop using just the battery, when start x the rainbow screen of death appears and the keyboard, mouse and all don't work anymore. If I reboot the laptop with the powe cable connected, all works great.
Hi, I found this: amdgpu_device_initialize: DRM version is 2.50.0 but this driver is only compatible with 3.x.x. Maybe does the kernel load radeon instead of amdgpu driver? If I type lsmod, I get: Module Size Used by rfcomm 77824 14 ccm 20480 9 bnep 20480 2 binfmt_misc 20480 1 nls_iso8859_1 16384 1 uvcvideo 90112 0 rtsx_usb_ms 20480 0 arc4 16384 2 memstick 16384 1 rtsx_usb_ms videobuf2_vmalloc 16384 1 uvcvideo edac_mce_amd 28672 0 videobuf2_memops 16384 1 videobuf2_vmalloc videobuf2_v4l2 24576 1 uvcvideo videobuf2_core 40960 2 uvcvideo,videobuf2_v4l2 rtl8821ae 225280 0 videodev 172032 3 uvcvideo,videobuf2_core,videobuf2_v4l2 kvm 581632 0 btusb 45056 0 btcoexist 126976 1 rtl8821ae media 40960 2 uvcvideo,videodev btrtl 16384 1 btusb snd_hda_codec_conexant 24576 1 irqbypass 16384 1 kvm snd_hda_codec_hdmi 49152 1 snd_hda_codec_generic 73728 1 snd_hda_codec_conexant btbcm 16384 1 btusb btintel 16384 1 btusb rtl_pci 28672 1 rtl8821ae crct10dif_pclmul 16384 0 snd_hda_intel 40960 5 rtlwifi 77824 3 rtl_pci,btcoexist,rtl8821ae crc32_pclmul 16384 0 snd_hda_codec 126976 4 snd_hda_intel,snd_hda_codec_conexant,snd_hda_codec_hdmi,snd_hda_codec_generic ghash_clmulni_intel 16384 0 mac80211 778240 3 rtl_pci,rtlwifi,rtl8821ae bluetooth 544768 41 btrtl,btintel,bnep,btbcm,rfcomm,btusb snd_hda_core 81920 5 snd_hda_intel,snd_hda_codec_conexant,snd_hda_codec,snd_hda_codec_hdmi,snd_hda_codec_generic pcbc 16384 0 aesni_intel 188416 6 ecdh_generic 24576 1 bluetooth aes_x86_64 20480 1 aesni_intel snd_hwdep 16384 1 snd_hda_codec crypto_simd 16384 1 aesni_intel glue_helper 16384 1 aesni_intel joydev 20480 0 input_leds 16384 0 snd_pcm 98304 4 snd_hda_intel,snd_hda_codec,snd_hda_core,snd_hda_codec_hdmi snd_seq_midi 16384 0 snd_seq_midi_event 16384 1 snd_seq_midi cryptd 24576 3 crypto_simd,ghash_clmulni_intel,aesni_intel serio_raw 16384 0 k10temp 16384 0 snd_rawmidi 32768 1 snd_seq_midi fam15h_power 16384 0 wmi_bmof 16384 0 snd_seq 65536 2 snd_seq_midi_event,snd_seq_midi snd_seq_device 16384 3 snd_seq,snd_rawmidi,snd_seq_midi snd_timer 32768 2 snd_seq,snd_pcm cfg80211 610304 2 mac80211,rtlwifi i2c_piix4 24576 0 ideapad_laptop 32768 0 snd 77824 21 snd_hda_intel,snd_hwdep,snd_hda_codec_conexant,snd_seq,snd_hda_codec,snd_timer,snd_rawmidi,snd_hda_codec_hdmi,snd_hda_codec_generic,snd_seq_device,snd_pcm shpchp 36864 0 mac_hid 16384 0 tpm_crb 16384 0 soundcore 16384 1 snd sparse_keymap 16384 1 ideapad_laptop parport_pc 32768 0 ppdev 20480 0 lp 20480 0 parport 49152 3 lp,parport_pc,ppdev autofs4 40960 2 btrfs 1093632 0 xor 24576 1 btrfs raid6_pq 118784 1 btrfs dm_mirror 24576 0 dm_region_hash 20480 1 dm_mirror dm_log 20480 2 dm_mirror,dm_region_hash amdkfd 184320 2 amd_iommu_v2 20480 1 amdkfd amdgpu 2007040 12 rtsx_usb_sdmmc 28672 0 rtsx_usb 20480 2 rtsx_usb_sdmmc,rtsx_usb_ms radeon 1474560 1 hwmon 16384 4 fam15h_power,amdgpu,radeon,k10temp i2c_algo_bit 16384 2 amdgpu,radeon ttm 94208 2 amdgpu,radeon drm_kms_helper 159744 2 amdgpu,radeon psmouse 143360 0 syscopyarea 16384 1 drm_kms_helper sysfillrect 16384 1 drm_kms_helper sysimgblt 16384 1 drm_kms_helper fb_sys_fops 16384 1 drm_kms_helper drm 348160 8 amdgpu,radeon,ttm,drm_kms_helper ahci 36864 3 libahci 32768 1 ahci r8169 81920 0 mii 16384 1 r8169 wmi 24576 2 wmi_bmof,ideapad_laptop video 40960 1 ideapad_laptop What do you think, should I blacklist radeon driver?
(In reply to MaxV from comment #6) > Maybe does the kernel load radeon instead of amdgpu driver? Yes, the attached working dmesg shows the radeon driver being used for the discrete GPU (the APU is only supported by amdgpu). > What do you think, should I blacklist radeon driver? As of kernel 4.13, it's better to use amdgpu.si_support=1 radeon.si_support=0 instead of blacklisting.
Here is a video of the bug: https://youtu.be/Lnj2_AgQ7WU
Hi, I noticed that linux kernek had some errors about CPU/motherboard identification at startup, so I upgraded the motherboard BIOS and now the bus seems disappeared.
