[SOLVED] I have installed Slackware in an external SSD and in one of my PCs, booting delay 40 min

micalmar · 03-09-2024, 06:14 AM

Hello everybody
I have installed Slackware 15 in an external SSD
I have 3 Pcs and Slackware boots normaly in the other 2.
In my desktop computer the booting in bios mode or Uefi mode is not more long than booting Debian or ArchLinux.
I have a modern laptop (2022). It boot in Uefi mode only fastly.
The problem is in my acer aspire with

single core Intel Celeron 743

Booting delay more than 30 min. I have tried booting with lan cable connected and without it and can't appreciate differences
This same laptop has Lubuntu installed in an internal SSD and boots quickly
with Debian or Archlinux from an external SSD it boots also without duration problems

Some settings of my laptop:

I don´t know where begin to search where the problem is

External SSD connected how?

I wonder if your problem overlaps mine somehow. The ages of CPUs and BIOS is similar, 2006-2009.

Whenever you post command output here, always include the input command and the output formatting, as described here, contained within code tags please.

Booting delay more than 30 min.

Which boot loader (lilo, elilo, grub)?

What do you see on the screen during the 30 minutes? Does the boot loader take that time to load vmlinuz and initrd.gz or do the kernel messages take that time? If there is a long pause, what was it doing before that and what will it do after the pause?

Whatever bootloader you use, I'd try adding a menuitem to allow choosing between the Generic and the Huge kernel to note any difference. It is possible that for one example the generated initial initrd used by Generic or lack of one for Huge could make kernel locating the drive and it's partitions take a long time. Race them!

The external SSD is connected by USB 2
The boot loader is grub Bios Mode

it start with

Code:

linux /boot/vmlinuz... root=UUID=XXXXXX ro

I have put echo 'before '
and echo 'after'
after the command

Code:

initr /boot/initrd.z

in the display i can read
decompressing linux
somme lines are displayed and stoping with the last line :

Code:

[    1.307181 Freeing initrd memory: 9684K

and there is a first pause
some minutes after

Code:

[    1.583272 clocksource: tsc: mask: 0xffffffffffffffff max_cycles: 0x12b151e6acd, max_idle_ns: 440795227649 ns
[    1.583390 clocksource: Switched to clocksource tsc

some minutes after

Code:

[    1.929166 random: crgn init done

last pause
and after it continues dispaying lines until x session start

Petri Kaukasoina · 03-10-2024, 05:44 AM

What clock sources are there?

Code:

cat /sys/devices/system/clocksource/clocksource0/available_clocksource

Try other than tsc. In /etc/default/grub, change line GRUB_CMDLINE_LINUX="" to, for example, GRUB_CMDLINE_LINUX="clocksource=hpet" or GRUB_CMDLINE_LINUX="clocksource=acpi_pm". (And run grub-mkconfig -o /boot/grub/grub.cfg).

(The numbers like 1.929166 are seconds from the kernel start, and now your clock seems to be ticking like 100x too slow.)

I have add added in the grub command :

Code:

clocksource=hpet

and now the Boot delay normally (same as others Distros)
thanks writing the lines i could see in the display gave me a trail to follow.
