Hi! I have recently bought ubuntu pc stick PCG02U from MeLE, and struggling with it since then. It have z3735f atom processor and 32G eMMC drive. Originally it was going with ubuntu desktop 14.04 and 3.16 kernel, but it had problems with some sporadic eMMC errors under high drive load. Then I have upgraded it to ubuntu 14.04.4 with 3.19 kernel, and eMMC errors seems to be gone (not sure though), but now I faced freezes. It have never freezed while being in use, but after I leave it running for about 6 hours or more, I always find is freezed then. Monitor doesn't show any signal (guess cause it gets freezed in sleep) and no reaction on keyboard and mouse options. after reboot I see: [ 7110.326234] RTL8723BS: nolinked power save enter [ 7171.775617] RTL8723BS: nolinked power save leave [ 7173.461854] RTL8723BS: nolinked power save enter [ 7234.832616] RTL8723BS: nolinked power save leave etc.... stops at some point of time, and normal boot messages then in kernel.log
Have tested 16.04 with original kernel then, and with upgraded to 4.7.0 kernel, all the same. Trying intel_idle.max_cstate=1 option now but not much time have passed to see wether it helped. Will report it later. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1575467 Title: [Dell Inspiron 3451] WARNING: CPU: 1 PID: 1297 at /build/linux-lts- utopic-vy2yyy/linux-lts- utopic-3.16.0/drivers/gpu/drm/i915/intel_display.c:1743 vlv_wait_port_ready+0x126/0x170 [i915]() To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1575467/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
