https://bugzilla.kernel.org/show_bug.cgi?id=97931 Bug ID: 97931 Summary: GPU lockup with Radeon HD 4670 Product: Drivers Version: 2.5 Kernel Version: 3.16.0-4-amd64 #1 SMP Debian 3.16.7-ckt9-3 (2015-04-23) x86_64 GNU/Linux Hardware: x86-64 OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@xxxxxxxxxxxxxxxxxxxx Reporter: joe.r.floss.user@xxxxxxxxx Regression: No Created attachment 176201 --> https://bugzilla.kernel.org/attachment.cgi?id=176201&action=edit xserver-xorg package info Hello, I have a bug that regularly happens when running FlightGear (which uses OpenGL a lot). The kernel messages are very similar to those from bug 68571 ("GPU lockup on AMD Radeon HD6850 with DPM=1"). The symptoms are: screen goes blank for a few seconds, reappears, goes blank again, reappears garbled, alternates between blank and garbled a few times, and if I don't reboot quickly enough, I seem to recall (not sure about this one) that the whole system may crash in a way that requires a hard reset. My kernel command line is: BOOT_IMAGE=/boot/vmlinuz-3.16.0-4-amd64 root=UUID=... ro init=/bin/systemd ipv6.disable=1 This bug is present on Debian unstable, I had it yesterday; it is also present in the just-released jessie. I am attaching the kernel log from yesterday's occurrence of the bug. My graphics adapter is: 01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] RV730 XT [Radeon HD 4670] (prog-if 00 [VGA controller]) Subsystem: PC Partner Limited / Sapphire Technology Device e100 Flags: bus master, fast devsel, latency 0, IRQ 50 Memory at e0000000 (64-bit, prefetchable) [size=256M] Memory at fb9e0000 (64-bit, non-prefetchable) [size=64K] I/O ports at be00 [size=256] [virtual] Expansion ROM at fb900000 [disabled] [size=128K] Capabilities: [50] Power Management version 3 Capabilities: [58] Express Legacy Endpoint, MSI 00 Capabilities: [a0] MSI: Enable+ Count=1/1 Maskable- 64bit+ Capabilities: [100] Vendor Specific Information: ID=0001 Rev=1 Len=010 <?> Kernel driver in use: radeon If there is something I can test to help solve this bug, please say so. I wonder if there are graphics adapters with decent OpenGL support using free drivers that don't suffer from this kind of bug...
