Random Reboots

[thriller]

I was hoping to get a feel of the frequency people experience with random reboots on their PBP.

This past week I experienced three random reboots when using my Pinebook Pro.  All three times the laptop was running on battery at the time.  The first time I had just turned it on and started browsing the web for less than five minutes (Performance Mode was enabled for the CPU and battery was 100%).  The second time I was downloading about 10-15 PDF files while listening to music and browsing Reddit (On-Demand Mode was enabled for the CPU and battery was 100%).  The third time happened about 20 minutes after waking it up from suspend and browsing a website while doing a little bit of scripting (On-Demand Mode was enabled for the CPU and battery was 85%).

All three of these scenarios seem to consume different amounts of power but yet all led to the same issue.  Has anyone else experienced these issues in a similar or even different fashion?  Any guesses as to why this might be occurring?

Spec info: Default Debian OS with latest firmware update and standard 64GB eMMC.  I did flash my eMMC a month ago due to screwing around with installations.

I experienced two reboots this week and others in past weeks.

The most recent, about 15 minutes ago, happened while I was logging into a website. I had four other tabs open, as well as a terminal window and keepass2. Nothing seemed out of the ordinary. My mouse and keyboard stopped working, the screen went black and rebooted.

I am running the stock OS and just updated with Mr. Fixit's script yesterday.

I'm guessing this is a kernel panic, but I have very little experience diagnosing this type of issue. Perhaps someone will chime in with some pointers.

I got a bunch of this in dmesg right before the latest reboot:

Mar  7 16:31:20 PinebookPro kernel: [146439.023439] cp15barrier_handler: 30 callbacks suppressed

The next event shows the PBP booting:

I've been experiencing a lot of random reboots as of the past week. This morning it's occurring when I turn on the machine and a minute after logging in it goes to the full screen terminal with a flashing "_", and then shuts down. As well I've had issues where the screen turns grey and white (which appears like a video driver display issue, but since they're occurring together, perhaps the issues are linked?) Both of these started happening after I installed code-oss & extensions for it, but again I'm not sure of the causation.

here's a picture of the grey screen. Usually there's more white & distortion but I haven't got a picture of that

& it happened again and i've realized it makes a high pitch noise when this happens. it seems to not be charging now as well? i love this laptop i don't want it to die!

I've experienced two random reboots myself in the past month or so (while on battery), but haven't been able to get any useful information out of the system logs. When I checked, the last entries seem to be unremarkable, followed by a line of garbage and then kernel boot messages. Am using mrfixit debian and am up to date. (Wonder if there might've been something in the last update?)

I've had a couple (around 3) the last month or so... Never when I was doing anything special. Last time it happened the mouse pad stopped responding a couple of minuttes before. I had to work on so I plugged in a mouse which worked fine until the reboot happened.
After that the mouse pad was fine again too

I experience random reboots as well. Not often and always random. Sometimes on battery, sometimes not. I'm running the default OS.

I have encountered that also.
