https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D270888 Cy Schubert <cy@FreeBSD.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |cy@FreeBSD.org --- Comment #7 from Cy Schubert <cy@FreeBSD.org> --- I've had this problem for years ever since the switch from native FreeBSD D= RM to Linux KPI DRM. The machine may panic with a page fault in DRM. Other tim= es the machine will hang (freeze), while other times the i915 (HD3000) GPU will itself panic, as seen in the occasional core dump produced by the panic. Ea= ch of these panics, freezes, GPU panics are accompanied by X apps that use GPU acceleration appearing with blotchy streaks or blobs on them. The apps incl= ude mate-terminal, claws-mail, exmh2, firefox, and chromium. Xterm and CDE dtte= rm will not, because they do not use the GPU. The problem is more apt to occur when performing a lot of I/O from/to disk, like installworld. The problem a= lso occurs when a browser is loaded in memory, probably due to the amount of me= mory browsers use. Setting hw.i915kms.enable_dc=3D"0" to device.hints has eliminated/reduced t= he occurrence of the GPU freezes and GPU panics, though it is probably too ear= ly too tell as I just added this to device.hints. I'll have a better feel for whether this circumvention resolves my problem or not. My problem may or may not be this problem and could be unique to the HD3000 i915 GPU. I don't know. Avoiding apps which rely on the GPU while a browser= is running or while performing a lot of I/O to disk, SSD, or USB disk reduces = the likelihood of the problem occurring. Using apps which do not use the GPU totally circumvents the problem. --=20 You are receiving this mail because: You are the assignee for the bug.=
