Title: Unable to boot kernel 4.5.2-towo1
Post by: bokoto on 2016/04/22, 11:49:05
I upgraded manually to linux 4.5.2 yesterday from 4.4. but I cant get it to boot - I get a blank screen with no errors and it hangs there forever. I can go back and boot 4.4 fine. The initrd and vmlinuz files are in the boot directory as expected. Grub sees the new kernel and lists it in the boot menu. Grub.cfg seems pretty much standard and i haven't touched it. I have a UEFI setup running LXQT. Any ideas will be appreciated!

hwinfo | grep -A 14 "VGA compatible controller (VGA)"or
Code: [Select]
inxi -Gor

lspci -v  | grep -A 1 "VGA compatible controller"

Perhaps, try also grub start parameters

Code: [Select]
i915.modeset=0
or
nomodeset


In my case it was a computer of a friend of mine with the same (?) Intel Corporation 4 Series Chipset Integrated Graphics Controller, which booted into a black screen after installing a new kernel.

Can you try


apt purge xserver-xorg-video-intel


and reboot?


And please, do not disable KMS for that.

Hello, Thanks for the suggestion - however removing the xorg video intel did not solve the issue. I still get the blank screen after grub. On the other hand, I tried the clearlinux 4.5 kernel and it booted ok but then it comes up with some warnings about powerclamp intel not supported on my cpu ,and subsequently turns off lxqt power management so I have no battery detection at all. Apart from that I still have not been able to boot any 4.5 siduction kernel.

Please boot again with 4.5 and hit "e" at grub-screen, then navigat to the line which begins with linux and remove quiet from that line, hit ctrl +x to boot up now. Hopefully you see some relevant messages without the "quiet" which helps to investigate, whatÄs going wrong.

I have removed the quiet from the grub linux line - nothing happens - normally there would be some disk activity but here nothing - just a blank screen with the backlight on, no cursor. and It just doesn't progress from here. No warning no errors, nothing.

Hi, thanks for your response
 i915.modeset=0 results in non-bootable system - so I guess it is not KMS that is causing the problem

Ok so far just a summary - 4.4.0/1 boots always ok - no errors, 4.5 clearlinux boots ok with no power management , 4.5.1/4.5.2 siduction does not boot at all - no errors no warnings - <i tend to believe there must be something unrelated to the video driver since if this was the case, i would normally get some artifacts at boot screen.


Ok finally something  - I installed
4.5.0-1-amd64 #1 SMP Debian 4.5.1-1 (2016-04-14) x86_64 GNU/Linux


and it booted just fine - i will stick to it for now and possibly continue with the towo - siduction kernels when i get the time .
