Bootloader pauses before counting down on UEFI motherboard

lawrent · 2015-01-23 21:09:11

Hi,

I recently installed Arch Linux on my new computer and, strangely, the computer freezes for a moment before the bootloader counts down. I'm surprised by this because before installing Arch, Windows 8 would launch within a couple of seconds (I have a SSD disk).

Here's the output of systemd-analyze:

Startup finished in 3.076s (firmware) + 11.176s (loader) + 1.477s (kernel) + 15.204s (userspace) = 30.935s

(note that the bootloader's timeout is 5 seconds, so the loader freezed more than 6 seconds.)

I've had the same issue with Gummiboot and GRUB. I'm not familiar yet with debugging/analyzing tools, could someone help me to dig into this bug?

Thanks!

Edit: maybe a useful info: my computer is a Toshiba Satellite Z30t

Install gummiboot (if it isn't running already), set the "timeout" to zero in loader.conf then hold down the space bar during boot-up, press "t" and set the timeout to zero from the gummiboot menu.

What is the `systemd-analyze` output when you reboot again?

note: pressing "t" at the gummiboot menu increments gummiboot's timeout, pressing "T" decrements it.

After disabling gummiboot's menu (pressing "T" till countdown is zero), systemd-analyze gives

Startup finished in 3.141s (firmware) + 6.112s (loader) + 1.665s (kernel) + 1.987s (userspace) = 12.905 s

i.e. the loader still takes the main part of the setup.

Try making a manual NVRAM entry using efibootmgr & boot from that, see if that has a delay as well.
https://wiki.archlinux.org/index.php/EF … bootmgr.29

If there is still a delay, I think it must be down to your firmware...

I guess all those entries come from the trial-and-error I went through when installing my bootloader. Could it be possible that they are responsible for my setup delay?

Head_on_a_Stick · 2015-01-24 20:10:18

It's possible --you can remove unwanted entries using:

# efibootmgr -b xxxx -B

lawrent · 2015-01-24 20:14:13

Thanks for the tip! Not much time to test right now, but I'll try it out

TheSaint · 2015-01-25 03:00:29

The BIOS timeout is 1 second, I don't know whether it's related to gummiboot. Do the other boot loaders respect their timing ?

PS, see whether this may help you.

Just removed some unnecessary entries (the 3 Syslinux ones, the second Windows one and the grub-uefi one) and systemd-analyze still gives me 6seconds spent on the booter.

I read your PS, TheSaint:
- Tried adding a /boot/loader/entries/windows.conf, no effect. (Except that now I have an additional Windows option on Gummiboot's menu.)
- Updated the BIOS' firmware (via Windows), no effect.
- the guy wonders if the problem comes from the Ubuntu installer he used to resize his disk. I used GParted, but I'd be surprised that it's the cause of the problem.
- timeout is set to 0 in /boot/loader/loader.conf

About https://bbs.archlinux.org/viewtopic.php?id=192272 you first mentioned, Head_on_a_Stick,
/boot/EFI/Boot/bootx74.efi and /boot/EFI/gummiboot/gummiboot.efi are identical

I'll try to make a boot option manually with efibootmgr next time, now it's time to go to job.

TheSaint · 2015-01-27 09:00:18

Booting win8 was by the mean of fastboot option in the BIOS, I think.
Very similar you may achieve if you use to hibernate Arch to disk.

lawrent · 2015-01-31 09:01:46

I tried making a boot entry directly with efibootmgr, (cf https://wiki.archlinux.org/index.php/EF … bootmgr.29 ). No boot menu on screen this time but still the 6 seconds delay…

Is there a log of what is done during the boot part of the setup, to see if there's an error occurring?

If it still occurs with a direct NVRAM entry, then it's because of your firmware -- you could try updating it but I think you can only do that sort of thing from Windows.

Does your firmware have an option for "Intel Fast Start"?

This requires a special partition on the hard drive and cannot be used with GNU/Linux; you could try disabling that, it may be searching for the extra partition in those six seconds.

lawrent · 2015-01-31 12:15:08

BIOS has already been updated from Windows
Found "Intel(R) Rapid Start Technology" option in the Setup Utility, disabled it, didn't fix my delay.

TheSaint · 2015-01-31 22:13:00

I think the delay is after the kernel loaded. That's why is shown by the journal.

joaocandre · 2015-02-12 14:09:59

Same problem on a Toshiba laptop - similar setup, dual booting between Arch and Windows.

joaocandre · 2015-03-13 15:40:10

No updates about this issue? It's not something that really bothers me since I rarely reboot, but anyway I'd love to find a solution.

unixman · 2015-03-13 19:35:52

my ivybridge with gummiboot.

me@~: systemd-analyze
Startup finished in 7ms (firmware) + 158us (loader) + 4.322s (kernel) + 2.989s (userspace) = 7.320s
me@~:

It is microsecond.

fabb · 2016-02-21 20:24:52

Similar issue on my Toshiba Z30 with GRUB:

Startup finished in 5.148s (firmware) + 11.447s (loader) + 1.357s (kernel) + 2.449s (userspace) = 20.403s

Did anyone find the reason?
