Created attachment 153551 [details] full dmesg Hi, I've bought recently a MSI R7 265 (lspci attached), and use it in build under Debian testing. I've tried to configure it in order to have H264 hardware decoding, but UVD failed at boot time (dmesg attached). I've tried to boot with dpm=0, the problem is still here. As one user had problem with maybe overheating (https://bugzilla.kernel.org/show_bug.cgi?id=60858), I changed the thermal paste on my graphic card, but the problem persists. I've dumped some registers, as it seems to be interesting : root@steambox:~# radeontool regmatch 0x0718 0x0718 0x00000023 (35) root@steambox:~# radeontool regmatch 0x071c 0x071c 0xc080001c (-1065353188) root@steambox:~# radeontool regmatch 0x0720 0x0720 0x3168680e (828925966) Thanks for your help !
