Latest update will not boot

I’m not sure what will be easier, figuring out how to get the latest update to boot or trying to roll it back.
After the latest update it required a restart, which I did, and now freezes at “loading initial ramdisk…” for kernel 4.4.143-65-default.
I am able to get back in using kernel 4.4.140-62-default, so I haven’t lost anything yet.
Any ideas or wisdom would be greatly appreciated.

Nvidia Driver is installed?

Yes. Now to add text to get 10 characters.

Try as root:

zypper in -f nvidia-gfxG04-kmp-default

Reboot.

No luck on that. I was kinda wondering as the display driver glitches generally show up later on in the boot sequence.

cat /var/log/Xorg.0.log

Maybe as Textfile…

Sorry “I may NOT post attachments” and the output is too long. I could take out things that don’t seem relevant, such as Wacom tablet, in an effort to shorten it but I’m not really adept at that sort of thing and could make a mess.

You can use the susepaste command from a rescue boot from installation media, or other means to upload the file to susepaste.org, and provide a link to the resulting URL here.

Thanks for that.

Hello forum,
I am also hit by this event - kernel vmlinuz-4.4.143-65-default stops loading when or after it loads the kernel image into the ramdisk.
It looks like a permanent freeze without reaction to anything (ctrl alt del, SysRQ-Reboot request). Only the reset button helps…

I can boot into the fallback kernel (vmlinuz-4.4.140-62-default) - but I cannot find any logs from the broken boot process (journalctl --boot=-1 does yield the last succesful boot with the old kernel where I can follow the session where the updates were applied).

I use NVIDIA proprietary drivers…

As I can work for now, this is not a big issue, but I can provide additional info if required to help to clarify the issue.
Note: the formerly requested Xorg-logs also do not contain any line from the broken boot - just the successful boots.

Greetings
Bernd

I had the same problem and found out that the problems is with tsc. Add the following kernel parameter to solve: tsc=unstable

Ok - that was fast… and it solved the problem for me, too.

Stupid question: why?
cpuid reports my CPUs to be TscInvariant, so that the CPU manufacturer - well - guarantees that CPU powermanagement details should not affect the TSC reliability.

And it seemed to have worked until the last update…

Anyway - problem mitigated for now…

Many Thanks!
Greetings

tsc-Time Stamp Counter is time source for the kernel. My guess is that a jitter is intentionally introduced to mitigate the meltdown and Spector CPU bugs. this apparently has some negative effects on some hardware. Pure guessing:P

The boot-up hanged on the following line: “Marking TSC unstable due to check_tsc_source failed”. The above parameter makes the boot process to ignore that check-up.

Exactly what CPU do you have. I run AMD CPU and have not seen the problem and just updated fully.

I think the issue is with the tsc_adjust flag. In other computers I have, on which boot up is OK this flag is absent.

Just to add my processor:

Maybe we have a setup with this processor and the surrounding hardware that causes unwanted side effects…
My system is running now on an alternative time source (hpet) which seems to work well…

If every i7 processor would be affected I guess that we would see much more feedback or issue reports. I assume that it is only a combination of processor and environment that causes this unwanted effect to appear.

At least we have a workaround and people can find it now.
