I have an Intel NUC NUC6CAYS updated to latest bios. The eMMC containing Windows is disabled and I've installed an SSD inside for Linux.
- BIOS is at latest version and "UEFI OS Selection" setting is "Linux".
- UEFI Mode
- Fresh install of
Ubuntu Server 17.04updated
It's working but sometimes the system hang after reboot. I did a tons of reboot to diagnose and when it happen it's always right after GRUB menu.
I tried to:
- Hold SHIFT
- Hole ESC
- Press CTRL+ALT+DELETE
Nothing work when it's freezed, I have to long press the power button to shut it down and restart.
So far, I tried many GRUB settings without success (nomodeset, max_cstate):
GRUB_DEFAULT=0
#GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT=2
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="nomodeset intel_idle.max_cstate=0 processor.max_cstate=1"
GRUB_CMDLINE_LINUX=""
GRUB_RECORDFAIL_TIMEOUT=2
The problem was also in Ubuntu Server 16.04.02 LTS with Kernel 4.8, I updated to 17.04 to see if Kernel 4.10 was fixing it.
I can't find logs when this happen and journalctl doesn't log the boot tentative.
Update
I tried to install Ubuntu Server on a brand new SSD and I got the same Black screen freeze after selecting Install Ubuntu Server from the GRUB menu! I restarted and tried it but this time it worked. So it's really random and always after GRUB.
I've edited my \boot\grub\grub.cfg file on the USB to add debug loglevel=7 earlyprintk=efi :
menuentry "Install Ubuntu Server" --id ubuntu-server {
set gfxpayload=keep
echo "Installing...."
linux /install/vmlinuz file=/cdrom/preseed/ubuntu-server.seed debug loglevel=7 earlyprintk=efi ---
initrd /install/initrd.gz
}
Now I can see my early printk, after many reboots I finally reproduced the issue but the system hang right after:
[ 0.00000] Console: colour dummy device 80x25
[ 0.00000] console [tty0] enabled
[ 0.00000] bootconsole [earlyefi0] disabled
So it's not really helping me, freezing after earlyefi logs.
Thanks a lot for help
