soft lockup cpu on galaxy book s

[nullexistence]

[TheOneWithTheBraid]

Could you solve this? I got similar problems too, even though I tried newer kernels too (which should theoretically support the Snapdragon 8cx).

I found a workaround, it will sound absolutely insane but still.
I just plugged a second usb stick into the laptop.

My setup is:
Left usb port with installer
Right port with some random fat32 stick.
Have sadly no time to tinker atm and have done no more testing just saw that I was suddenly sitting in the Debian installer.

On a unrelated note. Does any one know what this image does differently to any other arm64 installer from other distros? Fedora and any other just reboot after grub.

Finally installed it, and got it to boot I to multiuser target

Charger is not working

[TheOneWithTheBraid]

For me, this didn't work. Could you maybe add some more words on what you did before?

In my case, the Grub simply reboots - even when having the second USB drive connected.

Did you use the Debian image linked in the release https://github.com/aarch64-laptops/debian-cdimage/releases/tag/v0.4?

What device tree blob did you load? Did you change any settings in the UEFI settings?

Yes, I used debian-unstable-arm64-DVD-1_20210314.iso
with no changes to device tree. While installing I used two usbc -> usba adapters with usb sticks. But later realized that one usbc -> usba adapter and my usbc -> ethernet adapter also did the trick.
Check the first photo by nullexistance. I get the cpu lockup from his photo everytime I have just one port occupied.

Edit:
I think it's a problem with power delivery and having those usb2.0 devices maybe somehow works around some problem.

[TheOneWithTheBraid]

Ah, I found my problem: Using a USB 3 drive simply didn't work. Switching to a USB 2 drive did the trick.

How did you manage to use debian-unstable-arm64-DVD-1_20210314.iso?

I dd'ed it to a flash drive and my boot menu doesn't pick up on it. I tried dd'ing a raw (not ISO) Fedora image and it detects it, but as noted above doesn't work.

Seems like my Book S doesn't detect any isohybrid images.

[misyltoad]

I committed some horrible sins and dumped the ISO contents all onto a vfat partition, and that at least got me to the soft lockup

The double USB trick worked here too, haha amazing!

[misyltoad]

I got the error "Failed to determine the codename for the release" but worked around by plugging in an ethernet cable to my Dock.

thanks for sharing the double usb trick !!

here are some newbie notes/questions :

apparently I still need the double usb trick to boot from internal ssd ...
... maybe this could be fixed by installing a newer kernel as told in https://github.com/aarch64-laptops/debian-cdimage ?? but which version ?? is 5.19 available ??

also gdm3 was giving me a black screen but I managed to open an alternative console (with "Ctrl Alt F2") and I installed the openssh-server to work more easily from another PC ... but I needed an ethernet cable to connect to the galaxy book S ... anybody has found how to connect the galaxy book S through wifi ??
... then I installed xfce and using lightdm worked to start my DEs !! (gnome was kind of slow but xfce feels faster ...)

also as @Systemscape said the charger doesn't seem to charge ... anybody found a solution to get the galaxy book S to charge ???
... and what tool can we use to check if the galaxy book S is actually charging ??

also from https://github.com/aarch64-laptops/debian-cdimage "Firmware installation" it looks like we need to load some kind of firmware for the galaxy book S to get some hardware blocks working ?? but how do we do that ??

thanks folks for any help !!

... oops ... sound doesn t seem to work ... did anybody find a way to make it work ??
... thanks again !

PS1 : installed the linux arm64 thorium browser (with google sync) from https://github.com/Alex313031/Thorium-Special/releases ... only 6725 in octane v2 (got about 32500 with Edge on Windows ...) ... chromium only 6493 ... firefox feels slow too ... anybody has an idea how to improve performance ??

15:39 <jenneron[m]> pierro78: i started to work on samsung galaxy book s, but it needs multi port usb for keyboard/touchpad, there are 5.19-based branches with support for it, but on 5.19 pmic arbiter fails..
15:41 <jenneron[m]> if you want to play around with it e.g. to bisect some kernel versions, you can use my dtb https://gitlab.com/jenneron/linux/-/commit/76f402e89cfb8308eb44822eda8fc816282d74a1, the latest version which works was 5.15 rc something

[misyltoad]

Something broke for me and now I always get dumped straight into grub minimal on the same flash drive I had working before argh
