Bug ID: 88481 Summary: Kernel oops leaves system without graphical output [radeon] Product: Drivers Version: 2.5 Kernel Version: v3.17.3 Hardware: x86-64 OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@kernel-bugs.osdl.org Reporter: daniel.otero@outlook.com Regression: No

When trying to start the X server through the the login manager, the radeon module seems to crash leaving the system without graphical output (but otherwise working). This happens every time as soon as PC boots.
Going back to v3.17.2 fixes the issue.
This seems to be relevant dmesg part:

--- Comment #1 from Christopher Frömmel cfroemmel@web.de --- I can confirm this. My laptop can boot with 3.17.3 with 2 additional monitors connected (DVI + HDMI) and all 3 screens are working. But when X is starting, kernel goes OOPS if HDMI is connected. I can reboot via ssh then. If HDMI is connected AFTER X has been started, system will enter a hard lockup state.
Will add my current .config and dmesg part.

--- Comment #10 from Adam Williamson adamw@happyassassin.net --- I'm not sure it's right to mark it as fixed until the patch goes to 3.17 - it's fixed in mainline, sure, but not stable. The fix seems to have missed the boat for 3.17.4. (I got burned by this with OpenELEC 5.0 beta 3, which happened to get kernel 3.17.3, and is commonly used on systems with Radeon graphics adapters and HDMI displays as it's an HTPC appliance distro...)

--- Comment #11 from Daniel Otero daniel.otero@outlook.com --- The bug is pretty nasty and the fix is quite trivial, so I don't know why wasn't included in the 3.17.4 release. I assume it's because didn't seem so urgent, but actually leave my system unusable.
I don't know the procedure to reach the current stable branch, but if it's going to be a 3.17.5 release, this fix should be in there. Should I mail Greg KH about the bug?
Anyway, I don't think leaving it open will make any difference.
