That patch you mentioned for me to try, according to that bug report, was ported upsteam into 3.18rc3 and i've been trying every kernel (both mainline debug and custom made with ehci support disabled etc) during the 3.18 cycle with varying amounts of success but never solving the power problems fully. When i gave up with 14.10 yesterday and installed 14.04 LTS, there isn't a single problem to be found anywhere the difference in stability is astounding.
#UBUNTU 14.04.2 NOAPIC BOOT OPTION INSTALL#
I discovered that all these acpi problems, errors for the keyboard, hiccups with ehci not behaving and most importantly: the backlight not working despite reconfiguring it and the machine not powering off properly were all caused as a result of a faulty EFI install of ubuntu 14.10 and _i think_ some systemd-logind bug or at the least inherent to a package in ubuntu 14.10 rather than kernel-side. Phew! It's been a long time since i last updated this report, and a lot of testing has happened but everything is at long last fixed.įirst of all, i think i should say what an absolute mess the UEFI/Boot settings are in.

I think we're close to narrowing down the issue(s) though! Unfortunately neither kernel seems to completely fix the issue 100%, as it still won't power off properly at shutdown? (See dmesg_after_patched_kernel.txt)ģ.14.21 also boots with no parameters set AND there's no warnings/errors (e.g. Results: Some success with patched 3.17.0 kernel! Can actually boot without any of the parameters set now, but still some errors/warnings recorded. Having seen a couple of messages suggesting this might be a regression from 3.15+, i also tried the latest 3.14 (3.14.21) from ubuntu's kernelmainline as well as building a custom 3.17 with the patch you linked to.

When I choose this option, the system hangs rightaway (blinking cursor on gray screen) or, if I choose the "Live (amd64 failsafe)" option, it starts to boot the kernel but hangs shortly after. When I try to boot from the USB pendrive on the Dell Inspiron, no EFI mode is available for the USB prendrive, so the only option is to run in LEGACY MODE. I am able to run debian live with no problems from this USB pendrive in a different, much older, laptop. I have disabled the Secure Boot option in the BIOS and prepared a USB pendrive with the following command (from a debian working system):ĭd if=debian-live-7.8.0-amd64-gnome-desktop+nonfree.iso of=/dev/sdb bs=4M sync However, so far I have not been able to run any debian live on the laptop.
#UBUNTU 14.04.2 NOAPIC BOOT OPTION WINDOWS#
I would like to run a debian live on my new Dell Inspiron 13 (7348) laptop (to check for hardware compatibility before installing debian in place of Windows 8.1).
