I don't know which kernel you call the Trusty kernel. I had problems with kernel 3.19. So i decided to test kernels 3.13,3.19,3.16, 4.2,4.4 and 4.5 as well.
after a look at http://packages.ubuntu.com/fr/trusty/kernel/, kernels 3.13,3.19,3.16, 4.2 are maybe trusty? So i will report with new tests for them. uname -a Linux portable-londe 3.13.0-77-generic #121-Ubuntu SMP Wed Jan 20 10:50:42 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux i got very boring boot errors: i2c-hid i2c-DLLC6AE failed to retrieve report from device since i tested this kernel a few minutes, i could not reproduce the cpu fifo error but i get another error instead, see below: dmesg|grep ERROR [ 0.502344] acpi PNP0A08:00: _OSC failed (AE_ERROR); disabling ASPM [ 1219.423486] [drm:drm_edid_block_valid] *ERROR* EDID checksum is invalid, remainder is 144 it occurs when i unplugged the hdmi cable and then plug it again. except that, everything seems to work correctly. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1542934 Title: [drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU pipe A FIFO underrun To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1542934/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
