Hi,
I've been experiencing PC freezes for a while now lately and only recently managed to enable the netconsole kernel module to send dmesg lines to a different PC in order to see what's happening. It seems that the cause of these freezes are kernel panics caused in the amdgpu kernel module at the dcn10_set_drr function. Is this a me problem or should I open a ticket on a bug tracker?
