--- Comment #7 from Václav OvsÃk <vaclav.ovsik at gmail.com> --- Bing - HDMI audio is probably a source of problem. I tried to add radeon.audio=0. I tested this before already, but I tried this time again with 4.9-rc7. No bug in console appeared, but kernel lock down (<Alt>-<SysRq>-B don't worked). I tried I think 3-times - no OOPS on console, only hang. Then I get idea to look into BIOS if HDMI audio is enabled there and really, HDMI was disabled completely. I enable HDMI in the BIOS and disable HDMI audio only and system started normaly. I tried combinations: BIOS BIOS radeon.audio=0 HDMI HDMI audio ---------------------------------------------------------------- 0 - no OOPS 0 - yes OOPS yes yes no OOPS yes yes yes OOPS yes no no OK So to avoid problems with the radeon driver the HDMI audio must be disabled in BIOS and it is possible only if the HDMI connector is enabled, because otherwise the option (HDMI audio) is greyed. I can't remember if I had this setting in the past, maybe yes. Disabled HDMI may be the result of BIOS "Load system default", because other flaws on this mobo with networking some time ago (. -- You are receiving this mail because: You are the assignee for the bug. -------------- next part -------------- An HTML attachment was scrubbed...
