syslinux fail to initialize ptp_kvm

Porske · September 8, 2023 at 6:11 PM

Hi,

during boot time I receive this error.

After POST it stuck here for about 1+ min

then the error appear for a fraction of a sec

and finaly kodi start as nothing was appended.

I have install LibreELEC Generic legacy 11.0.3 on my Packard Bell EasyNote TM85 JO 198IT with a 64Gb Kingston SSD and 4Gb RAM

Here some logs:

dmesg (you can se the error at [ 1.300040] fail to initialize ptp_kvm)dmesg.txt

At the end LibreELEC boot as normal and I can watch movies, listen music ecc... the annoying part is the 1+ min boot time every start... it's unbearable.

I don't know what else I can do, if you need more info just ask.
Thank you.

a) With kernel 6.1.38 the message fail to initialize ptp_kvm is printed at any boot on non-ARM systems. Ignore it.

b) dmesg is not showing the complete boot process, please use journalctl or better pastekodi for most complete logs.

c) My wild guess: kernel load via systinux is very slow or kernel initialization stuck for some time. To see more please do:

Code

mount -o remount,rw /flash
nano /flash/syslinux.cfg

and replace quiet with debug and reboot.

Porske · September 10, 2023 at 11:16 AM

Hi,

thank for the quick response.

Here it is pastekodi.txt and journalctl.txt

When i enable debug mode during boot it stuck here for the same 1+ min before start kodi

I don't think I saw the usual error ptp_kvm

**mglae** · September 10, 2023 at 10:54 PM

With "early console in setup code" kernel Real Mode initialization has started. But I've no idea what is causing the delay. Later kernel boot is OK.

You may try updating to LE 11 nightly with a more recent kernel.

Porske · September 29, 2023 at 11:09 AM

Hi,

I'm on the latest nigtly LibreELEC-Generic-legacy.x86_64-12.0-nightly-20230929-0a666e5.img.gz but I always have the same problem

pastekodi trow an error

Code

LibreELEC:~ # pastekodi
terminate called after throwing an instance of 'std::runtime_error'
  what():  No modesetting DRM card found
Aborted (core dumped)

add this is journalctl.txt

I have just test debian 11 with kernel 5.10 and upgrade to debian 12 kernel 6.1.0, boot like a charm there is no trace of ptp_kvm error in journalctl.

Does the old Libreelec generic 10.0.4 image contain nvidia drivers?

ptp_kvm is a module in their kernels and not loaded.

Still no idea what is causing the hang.

Yes.

I guess you have to downgrade LE to get the right NVIDIA driver: Click!

You can ignore that. It's just default log spam when the Xorg and driver ABI versions aren't quite aligned. If you get output (Kodi starts) things are working enough to ignore the warning.

I'd go back to the LE10 image and run "systemd-analyze plot > /storage/boot.svg" and then export the .svg file generated and open it in a browser. It will show a graphical display of the boot process and might flag where something's hanging and/or timing out.

**mglae** · September 30, 2023 at 8:55 AM

Kernel boot is a black box (just one grey line) in svg plot and will not include further information.

**mglae** · September 30, 2023 at 9:40 AM

But kernel init calls can be measured: add initcall_debug log_buf_len=2M to kernel parameters and check dmesg/journal.

Porske · October 1, 2023 at 2:31 PM

Hi,

yesterday in a "why not" mode I install Arch to test something different, boot like normal but in journal i found different error repeated twice:

set 29 17:22:03 LillyELEC kernel: kvm_intel: VM_EXIT_LOAD_IA32_PERF_GLOBAL_CTRL does not work properly. Using workaround
kernel version 6.3.9-arch1-1

I don't know if it can help.

In the next days I will try LE 10, we will see.
