Phones reboot with Syncthing 1.30 under LineageOS 16 on HTC m8

Wow, good find :-). If we could narrow it down to detect affected systems by kernel version I could disable NAT automatically for those devices as a workaround.

ProactiveServices · October 9, 2019, 4:08pm

The flash storage in my ageing HTC One M7 was quite badly worn and sometimes, when Syncthing’ing or copying a lot of data, the phone would spontaneously reboot. After setting the rate limits to 4.5MBps (incl. on LAN) the reboots ceased. I figured this was a hardware watchdog of some sort. It was reliably only happening when I synced / copied 200MB+ of data continuously. Just thought I’d chime in with a data point.

wweich · October 9, 2019, 4:53pm

Just FYI: I had similar issues with my Moto X Pure, with a slow (and maybe bad) SD Card formatted for “internal storage”. Even deleting a big directory (tree) caused reboots.

khumarahn · October 10, 2019, 10:24pm

I downgraded, unchecked NAT traversal, then upgraded back to 1.3.0. Syncthing works now, this is very good. Of course NAT does not work, but that is a smaller problem.

klausenbusk · October 12, 2019, 1:26pm

@kisenberg @shscs911 @neden What kernel version are you on?

Catfriend1 · October 12, 2019, 1:54pm

For me it’s $ uname -a Linux localhost 4.9.112-perf-g947b410 #1 SMP PREEMPT Wed Sep 11 22:47:10 CST 2019 armv8l On Android 9

shscs911 · October 12, 2019, 4:22pm

Its a bit convoluted, but works for me. You can enable Airplane mode and open Syncthing. Then select Change Settings from pop-up → Select Run when device is in flight mode → Unselect Run on Wi-Fi → Go back to main screen → Select Settings. Now you can open Syncthing Options and uncheck Enable NAT Traversal. Now change the Run Conditions back to original for normal operation.

shscs911 · October 12, 2019, 4:24pm

I’m using a custom kernel called

Thunder Kernel
zzmoove governer.
Linux version 3.4.11.
Linaro GCC 7.3-2018.05.
SELinux Status : Enforcing

klausenbusk · October 12, 2019, 4:51pm

@Catfriend1 @shscs911 Could you run sysctl kernel.panic_on_oops=0, start Syncthing (with “NAT Traversal” enabled) and check dmesg? If there is anything relevant in dmesg please post it.

Catfriend1 · October 13, 2019, 12:56am

I don’t have root, but have enabled NAT for a while and didn’t observe a reboot. So MIUI 10.3 on Xiaomi mi8 works fine.

kisenberg · October 13, 2019, 6:03pm

Now, I have access to one of the phones. Kernel: Linux version 3.4.113-g2d8d797 (buildkite-agent@lineageos-buildkite)(gcc version 4.9.x 20150123(prerelease)(GCC)) #1 SMP PREEMPT Mon Sep 30 17:04:06 UTC 2019

Uncheck NAT in 1.3.0 works also for me.

neden · October 14, 2019, 10:26am

I’m on LeneageOS 15.1 with kernel 3.4.113-lineageos-gf8d7bda.

klausenbusk · October 17, 2019, 2:45pm

@kisenberg @shscs911 @neden If any of you are running a official LineageOS build, could you report it upstream?

shscs911 · October 17, 2019, 2:48pm

Sorry mine’s an unofficial DirtyUnicorn build. I’ll report it to the ROM developer.

klausenbusk · October 17, 2019, 9:24pm

With help from @khumarahn, I think we have found the fix. I’m pretty sure this change fix the issue: https://github.com/LineageOS/android_kernel_cyanogen_msm8974/commit/f44b4b19da1541fce8440ffa1e59cdb722cf10b5, so contact your ROM developers and ask them to apply the fix.
