https://bugzilla.kernel.org/show_bug.cgi?id=115291 Bug ID: 115291 Summary: system freeze on loading radeon module Product: Drivers Version: 2.5 Kernel Version: 4.5 Hardware: x86-64 OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@xxxxxxxxxxxxxxxxxxxx Reporter: duemig@xxxxxxxxx Regression: No Created attachment 210741 --> https://bugzilla.kernel.org/attachment.cgi?id=210741&action=edit kernel log captured via netconsole system freezes when radeon module is loaded: 1. screen goes black 2. I can hear the harddrive spin down 3. no reaction on key presses like Ctrl+Alt+Del 4. the graphics card's fans halt immediately and do not start again until the reset button is pressed 5. no kernel panic or error messages in kernel log captured via netconsole $ lspci 01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Curacao PRO [Radeon R7 370 / R9 270/370 OEM] (rev 81) The graphics card works with VESA or fglrx drivers, as well as on windows, so the hardware has to be alright. Steps to freeze the system: 1. start system with radeon module blacklisted 2. stop graphical login manager 3. log into the console and manually load radeon module (# modprobe radeon) I copy my bug report from the Arch Linux bugtracker [1] here, since I encountered it on multiple distributions (Arch Linux, Ubuntu) and on the 4.5 vanilla sources as well.
