Priority: medium Bug ID: 64867 Assignee: dri-devel@lists.freedesktop.org Summary: Hangs on Cayman (HD6950) when watching flash/using vdpau Severity: normal Classification: Unclassified OS: Linux (All) Reporter: serafean@gmail.com Hardware: x86-64 (AMD64) Status: NEW Version: git Component: Drivers/Gallium/r600 Product: Mesa
Created attachment 79658 --> https://bugs.freedesktop.org/attachment.cgi?id=79658&action=edit dmesg after X freeze
When watching a flash video (opera + flash-11.2.202.262 ) the kernel log starts filling up with [ 7009.603310] radeon 0000:01:00.0: GPU fault detected: 146 0x0e677004 [ 7009.603313] radeon 0000:01:00.0: VM_CONTEXT1_PROTECTION_FAULT_ADDR 0x00000000 [ 7009.603316] radeon 0000:01:00.0: VM_CONTEXT1_PROTECTION_FAULT_STATUS 0x00000000
to sometimes eventually hang the GPU. When this starts appearing there is graphic corruption everywhere. I also managed to reproduce this when playing back a video using mplayer with the vdpau backend. ( EnableLinuxHWVideoDecode=1 is commented out in /etc/adobe/mms.cfg)
I managed to get a dmesg output after the GPU hang (attached) and then tried to save what is in /sys/kernel/debug/dri/0 but not knowing which was important, tried to do it in a bash for cycle, and got a complete hang.
linux-3.10-rc1 mesa, libdrm, radeon ddx from git.
might be related to https://bugs.freedesktop.org/show_bug.cgi?id=62959 , but piglit just finished fine. (fine = didn't hang in this case, still a bunch of "radeon_gem_object_create:69 alloc size 1365Mb bigger than 256Mb limit" in the logs). Additional info : I have a dual screen setup.
Anything more you need, I'll be happy to provide.
