There is a file named watchdog in /root/dev howeverwhat to do with it?
Includes Manjaro 
No idea about the path.
Will have to check it myself.

didn’t know it was a systemd based,
then it must be linked to the name of some other service, might need to do some digging around…
@Yasir_Javed can you share the output of:

Further today I also tried to mask the wpa_supplicant service however as soon as i did that, nmcli and nmtui were unable to detect any wireless network.
When I try to remove/uninstall wpa_supplicant using pamac, it tries to uninstall a whole load of other plasma things which i suspect might break my OS so i didnt uninstall.
I think wpa issue is coming from upstream code changes.
You should try disabling wifi complete and see if that helps.

Yes, disabling /masking WPA service (not uninstall, just disable) fixes the problem and shutdown completed in few seconds…
I can also confirm the issue does not exist in Fenix built Ubuntu mainline, it uses kernel 5.10 however… Manjaro is on 5.12… Maybe it’s something new…
I’m even prepared for any hack script which disables the WPA on shutdown and re enables on boot, but I’m not exactly confident I can do it without breaking anything else.

Hi @Spikerguy
I can confirm that using linux-vim instead of Linux-RC solves the WPA supplicant issue completely. The problem only exists in Linux RC, FYI please.
Also in the Linux - vim, there is no problem of watchdog hanging during shutdown. The shutdown is very clean and fast on it. I hope Linux-RC fixes the issue soon because other than this WPA problem, everything else was pretty great in it.
Yes if is it an upstream issue then it will be fixed in the next release.
Can you confirm if you have Manjaro ARM running on ur emmc with linux-vim installed and you do not get any green screen issue ?
Please do share the output of the following commands
uname -alsblk
Thank you.
Right now I have linux-vim and Mesa-git and manjaro is on emmc, there is no SD or USB even inserted in my vim. on all resolutions, my colors are ok. I can take camera snaps tomorrow to show you.
Also tomorrow I will share the output of these commands too.

Ok thanks.
Just need to know the kernel version. Thanks.
Hi @Spikerguy
As promised, please see below for uname, lsblk, inxi, info centre and neofetch. Right now resolution is 1080p on a tv so borders are a little cut, but rest everything is great including colors…

Maybe in the new Linux - RC 5.12…we need below to reduce the boot 30seconds delay
Because this delay only exist on Linux RC 5.12…rc 5.11 was ok… And also the latest Linux - vim (5.11) is ok… You can try and reproduce same with below steps :
- Flash manjaro 20.12 from Krescue to emmc
- Boot into Krescue again and flash latest uboot-mainline
- Reboot to OS and install Linux-RC which will overwrite linux-vim
- Update all packages. At the end perform a reboot.
You’ll see the delay I’m talking about. Wait for it, it will eventually reach login, then install Linux - vim and reboot and you’ll face no delays…

Thanks for the debug, For now I don’t think this can be fixed as it is coming from upstream, until someone come up with the patch 
I do not have much time lately, but can ping some maintainers so ask for help like @chewitt

Use the analyse tools in systemd to see which service is causing the delay:
systemd-analyze plot > /tmp/plot.svg
eog /tmp/plot.svg
If you don’t have eog drop the svg file in a browser window and it will be rendered.
NB: I don’t run desktop Linux on any Khadas devices. I also don’t see any delays in boot, as I go from initial u-boot output to Kodi on-screen in about 10 seconds with 5.11.y and 5.12.y kernels. So if it’s a kernel issue, it’s a self-inflicted problem (perhaps defconfig).

Hi @chewitt
I plotted both with linux-vim (5.11) and linux-rc (5.12) and strangely enough, cant pinpoint any specific service.
It was not 30 seconds, rather 65s as the bootchart suggests. Normal loading of kernel takes 6seconds… I have attached both below, if you can have a look.
BOOTCHART NORMAL (linux-vim)
BOOTCHART DELAYED (linux-rc)
I also fetched dmesg for each kernel:
NORMAL DMESG (LINUX-VIM)
DELAYED DMESG (LINUX-RC)
I will search manjaro forums and archwiki if i can find something. Maybe it is an RC issue and in the next version it gets fixed on auto…

[ 64.477379] bootsplash: Failed to initialize.
^ that’s my guess 
3 Likes
Thank you. That is me being lazy or lack of time to migrate from bootsplash to plymouth 
Might take sometime off to look into this during the weekend.
@Yasir_Javed try removing this bootsplash.bootfile=bootsplash-themes/manjaro/bootsplash from
/boot/extlinux/extlinux.conf file
Then reboot.

Ok, let me try and revert
@Spikerguy @chewitt
ITS FIXED… Kernel booting in 1.5seconds now,… thats even faster than the stable kernel. 
BOOTCHART:
Current contents of extlinux.conf are:
LABEL MANJARO
KERNEL /Image
FDT /dtbs/amlogic/meson-g12b-a311d-khadas-vim3.dtb
APPEND initrd=/initramfs-linux.img root=LABEL=ROOT_MNJRO rootflags=data=writeback rw console=ttyAML0,115200n8 console=tty0 no_console_suspend consoleblank=0 fsck.fix=yes fsck.repair=yes net.ifnames=0
#APPEND initrd=/uInitrd root=LABEL=ROOT_MNJRO rootflags=data=writeback rw console=ttyAML0,115200n8 console=tty0 no_console_suspend consoleblank=0 fsck.fix=yes fsck.repair=yes net.ifnames=0 bootsplash.bootfile=bootsplash-themes/manjaro/bootsplash
I also think we can remove the last line starting with “#” in extlinux.conf, but probably best if someone reviews it. Currently it does nothing…

I am having problem updating Manjaro:
conflicting files:
- linux-firmware: /usr/lib/firmware/brcm/brcmfmac4356-sdio.khadas,vim2.txt already exists in filesystem (owned by kvim2-firmware)
After this,i removed kvim2firmware and then updated without issues.
