Kernel log 5.1.3 showing amdgpu drm crash

Experiencing the same problem. On boot with any kernel > 4.20, the graph=
ics is
not initialized, few scrambled lines appear at the bottom of the screen and
then the screen goes blank. The system actually boots as when I entered my
credentials (on the black screen) and did "cat dmesg > dmesg.txt&qu=
ot;, when I
rebooted with kernel 4.19 the file was there (I have attached it to this
thread). The relevant portion of the dmesg log is:

I can also confirm that as a workaround, removing/moving file
/lib/firmware/amdgpu/raven_dmcu.bin and regenerating the initramfs ("m=
kinitcpio
-p linux" on Arch linux) allows the 5.1.3 kernel to boot normally (I c=
an also
start an X session and everything seems to be fine) and there are no drm er=
rors
in dmesg anymore.

System:
HP ENVY x360 Convertible 15-bq1xx/83C6, BIOS F.20 12/25/2018
Kernel: 5.1.3-arch1-1-ARCH
Grub kernel parameters: amd_iommu=3Don iommu=3Dpt idle=3Dnomwait
