Anyone else seeing GPU lockups with 2.6.38.2?

[chrisr]

I've just raised this bug in the Kernel's bugzilla. Basically, the kernel froze once the screensaver kicked in, in what appears to be an unpredictable unrepeated fashion.

Not the same, but I'm getting something very close:

Problem disappears when I disable page flipping:

Option "EnablePageFlip" "FALSE"

(In your radeon device section in xorg.conf.)

Might be worth a try.

You might try the patches referenced in this bug:

[chrisr]

Aren't those patches for r5xx-r7xx?

My card is RV350.

Does the Xorg patch apply to 1.9.5? I am undirecting full-screen windows in Compiz.

[kernelOfTruth]

this only is specific for 2.6.38 based kernels, right ?

I'm asking this because I'm also seeing the display output locking up when playing flash while fullscreen

grep -v '^ *#' /etc/adobe/mms.cfg

AllowUserLocalTrust = 0


AutoUpdateDisable = 1


AVHardwareDisable = 1

DisableDeviceFontEnumeration = 1


DisableProductDownload = 1



FileDownloadDisable = 1

FileUploadDisable = 1

FullScreenDisable = 0





OverrideGPUValidation = 1

any idea ?

using adobe flash 64bit 10.3 beta, alpha or whatever



system is Gentoo ~amd64 multilib

thanks !

The drm patch is that bug is irrelevant for your card (2.6.38 final already has a similar patch for r1xx-r4xx). Your issue may just be a 3D driver bug. Does disabling pageflipping help? You might also try the xserver patch mentioned in that bug.

ok, reading thoroughly made it clear

thanks !

(I'm using 2.6.37.2 btw)

I'm still wondering why stupid flash makes the GPU hang in full flash (this also happened with fglrx while I still used it, btw)

so it seems flash is doing mean things to the graphics cards

Flash, or any other userspace program running without root privileges, cannot crash the GPU. Only the driver can do that.

I cannot reproduce this problem on demand.

The crash "just happens" sometimes when I leave the screensaver running. However, it seems that the Xorg patch does apply to the 1.9.5 xserver with a little fuzziness and so I am currently building myself some new Fedora 14 RPMs based upon xorg-x11-server-1.9.5-1.f14.src.rpm.
