This occu= rs even when minimal video operations are happening, for example simple scroll= ing on an Xterm will cause it. Once the temperature starts rising, it will stay elevated indefinitely until the X server is exited. The cpu frequency is not causing it because the temperature remains elevated above 60 deg C even whi= le the system is idle and the cpu frequency is idling at 800 MHz on a 2.1 GHz = cpu. Also the laptop fan and heatsink assembly is clean of any dust, is open with full airflow, and operating properly. When the acceleration is turned off in either driver ( "NoAccel"=3D"true" i= n the intel driver and "AccelMethod"=3D"none" in the Xorg modesetting driver ), t= he problem goes away. With no acceleration, fast terminal scrolling and/or high graphics operations will cause the temperature to elevate but quickly goes = back down once the graphics operations become idle. In comparison, with the acceleration turned on, once the graphics operation triggers a temperature rise, the temperature rises excessively and remains elevated in a seemingly runaway condition until the X server is exited. The excessive temperature runaway condition can damage the laptop and/or greatly reduce battery charge life. The work around is to run the Xorg built in modesetting driver with glamor acceleraton turned off. =3D=3D=3D The laptop cpu/os specs: FreeBSD 10.3-RELEASE #0 r297264: Fri Mar 25 02:10:02 UTC 2016 root@releng1.nyi.freebsd.org:/usr/obj/usr/src/sys/GENERIC amd64 FreeBSD clang version 3.4.1 (tags/RELEASE_34/dot1-final 208032) 20140512 VT(vga): resolution 640x480 info: [drm] Initialized drm 1.1.0 20060810 CPU: Intel(R) Core(TM) i3-2310M CPU @ 2.10GHz (2095.29-MHz K8-class CPU) Origin=3D"GenuineIntel" Id=3D0x206a7 Family=3D0x6 Model=3D0x2a Steppi= ng=3D7 =20 Features=3D0xbfebfbff =20 Features2=3D0x1dbae3bf AMD Features=3D0x28100800 AMD Features2=3D0x1 XSAVE Features=3D0x1 VT-x: PAT,HLT,MTF,PAUSE,EPT,UG,VPID TSC: P-state invariant, performance statistics real memory =3D 4294967296 (4096 MB) avail memory =3D 4043096064 (3855 MB) Event timer "LAPIC" quality 600 ACPI APIC Table: FreeBSD/SMP: Multiprocessor System Detected: 4 CPUs FreeBSD/SMP: 1 package(s) x 2 core(s) x 2 SMT threads cpu0 (BSP): APIC ID: 0 cpu1 (AP): APIC ID: 1 cpu2 (AP): APIC ID: 2 cpu3 (AP): APIC ID: 3 =3D=3D=3D --=20 You are receiving this mail because: You are the assignee for the bug.=
