hackeron, search for "intel_idle.max_cstate=1" in relation to this hardware; it's a workaround for random freezes which (some) people are encountering.

This is the unit: http://www.intel.com/content/www/us/en/nuc/nuc-kit-nuc5cpyh.html It boots beautifully on Ubuntu 15.04 and Ubuntu 15.10 with linux- image-3.19.0-34-generic -- but when I try to boot with linux- image-4.2.0-19-generic I simply see the following: https://www.dropbox.com/s/y2c9i87kafvwsq1/IMG_1476.jpg?dl=0 The keyboard stops responding after this line: systemd[1]: Started udev Kernel Device Manager. Here is output from lspci -vnvn < http://pastie.org/10596250 - I am running headless, so there is no Xorg (or any other X server) installed. - I tried adding GRUB_CMDLINE_LINUX="nomodeset" (also: noacpi noapic) - I tried disabling devices in the bios like audio - Tried selecting "Ubuntu, with Linux 4.2.0-19-generic (recovery mode)" from the list, it does not boot into the recovery console either :( - I tried installing a clean 15.10 version on a blank hard drive (with debootstrap so latest packages) I am able to boot if I add systemd.unit=emergency.target to the kernel line. I can run "systemctl start networking" for example and it works, but if I run "systemctl start apport" (or ssh even) - I see this and the system freezes: https://www.dropbox.com/s/gmpse7bx0c70e4v/IMG_1479.jpg?dl=0 I am not sure how to troubleshoot further. When I reboot and select Kernel 3.19, there is nothing in /var/log/syslog or journalctl from the failed boot :( Any suggestions? - EDIT: It seems downgrading from the latest PY0044 BIOS version to PY0043 allows me to boot the system, but it freezes if running "reboot" - more details in this bug report: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1522201 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1521749/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
