dmesg

Hello,

I have a Dell Inspiron with a Radeon R7 M260/M265 [Topaz XT] - as reported by
lspci, and I'm facing problems with GPU initialisation, rendenring it unusable,
it is not listed on `xrandr --listproviders`, for instance, althoug the driver
is properly loaded. Attached are `dmesg` and `lspci -k`. Please let me know if
there's something else I can do to help.

Thanks for any help,
