Rebooting on LinOS 21

[mfascioglu]

Swap creation complated and rebooted then swap is activated on boot. Device is opening successful but when writing some amount data on swap device is rebooting. I checked with Ram Truth app. Do you have any idea for this problem?

Hi, Could you elaborate on what you meant by "writing some amount data". were you trying to open some apps assumeing it would get added to swap?

[mfascioglu]

Thanks for the reply.

Yes, Swap creation and swap activation is successfully. when device uses created swap file, device is rebooting. (When 1-2 MB of a 4 GB swap file is used.)

same here, keeps Rebooting on lineageOS-21.0 now I don't know how to fix it, can't open magisk and uninstall, it just reboot before I could do anything...help

[yeezylife]

OK this time it gives me enough time to uninstall before it reboot again...at least I can still use my phone...

v2.0-a6 BETA - 4096_60_99999.zip

doesn't reboot anymore, in fact I think it works fine

[janithcooray]

@yeezylife check if it's actually working or if its on fail safe mode

When I use this old phone to play hearthstone, it alway freeze. now it never freeze anymore...so I guess its working?..but maybe just the reboot after installation releases more RAM

and by the way in v2.0-b2 Beta(4096_60_99999.zip) SWAP_FILE_PRIOR is the same as the SWAPPINESS. shouldn't it be 99999?

how to 'check if it's actually working or if its on fail safe mode'? I can't find anything like android/data/swap/swapfile.log the module is showed enabled in magisk after reboot

[yeezylife]

swaptotal: 0kb so it's not working at all?..

[janithcooray]

@yeezylife

go to adb shell as root and go

cat /data/swap/swapfile.log

this should show what happened. if its failing , then there's an incompatibility with the version of the swapon bin or it's non-existent at all. will you be able to contact me via email or telegram? it'll be handy if can send you custom configured zips to figure this out.

I think you can just post a zip file in the comment...

OK I figured this out it returns "Fri Oct 25 11:40:38 CST 2024"

still don't know if it's failing or not, it's just a date

[janithcooray]

It's failing as it doesnt show the part where swap starts. i'll try adding more log data to the file so we can find out whats wrong. i'll link a debug release

[janithcooray]

@yeezylife check https://github.com/janithcooray/lin_os_swap_mod/releases/tag/v2.0-c-debug-1 be careful, this is a debug version. uninstall once you get the /data/swap/swapfile.log

[yeezylife]

OK I‘ll have a try..I just hope I'll still be able to use my phone after this..

@yeezylife right, swapon file may be somewhere else, could you send me the link from where you downloaded this ROM

@yeezylife https://github.com/janithcooray/lin_os_swap_mod/releases/tag/v2.0-c-debug-2 see what happens with this one, it might actually start swap

@yeezylife thanks for the help, i will need some more assistnace to figure this out.

The swap bin is in the default path. not sure why it's not working at this point. Could you try this release. https://github.com/janithcooray/lin_os_swap_mod/releases/tag/v2.0-c-debug-3

Also could you see the output of the following on adb

swapon -v

or

swapon --version

and

ls -lah /data/swap/swapfile

it seems to work now

as for the following three oder on adb...

PS E:\Program Files\adb> .\adb shell swapon --version toybox 0.8.10-android

PS E:\Program Files\adb> .\adb shell "su -c 'ls -lah /data/swap/swapfile'" -rw-r--r-- 1 root root 3.0G 2024-10-27 18:06 /data/swap/swapfile （I set it in 3072mb in vars.sh）

[yeezylife]

now it starts to reboot.. as soon as it starts to use the swapfile

[yeezylife]

I guess I'll just give up ...hearthstone works now anyway..

[janithcooray]

@yeezylife thanks for your help. i will look for another way to debug this in the meantime. Sorry that this didnt work out for you

[janithcooray]

Marking as closed since fail safe will prevent reboot. It will instead disable the module function. If you encounter this issue please post on #33
