Whatever help you can provide know that it is truly appreciated! I will follow your suggestion and try a different kernel and report back my findings, thank you!

And here is an armbian-monitor with verbosity set to 7: https://paste.armbian.com/ubuxilosap

Thank you for your reply Igor, I have not changed anything, its using the same power supply it has been using for the past years! I had the SSH terminal open on it and just saw this random output: Message from syslogd@nanopim4v2 at Jul 24 20:22:20 ... kernel:[169328.590321] Internal error: Oops: 0000000096000004 [#2] PREEMPT SMP Message from syslogd@nanopim4v2 at Jul 24 20:22:20 ... kernel:[169328.616489] Code: 54000088 14000011 f9400273 b40001f3 (b9401a63) Not sure if it helps, but afterwards I took a new armbian-monitor capture: https://paste.armbian.com/huzanoyifi

I've recently upgraded my NanoPi M4 V2 to Armbian_25.2.1_Nanopim4v2_bookworm_current_6.12.13_minimal.img.xz and since that, I have been getting random crashing of it, to the point that I have to manually power it down and up again to get it back running again. The only thing I've noticed is that this normally happens when there is intensive disk usage (like downloading a bunch of docker images, or when downloading large files from the internet). Here's the output from armbianmonitor -u pedro@nanopim4v2:~/docker$ armbianmonitor -u Collecting info and sending to paste.armbian.com, wait... dmesg: read kernel buffer failed: Operation not permitted dmesg: read kernel buffer failed: Operation not permitted https://paste.armbian.com/jefilizufo Please post the URL in the forum where you've been asked for.

First of all, apologies if this has been asked before, I did search the forums and couldn't find anything related... My NanoPi M4V2 has an NVME still running Debian Buster and I have been delaying upgrading/flashing as I expect this to be not that trivial... My understanding is that the recommended upgrade path is to reflash the SD-card and start over, which is fine with me. However, I do want to ensure it will then again boot from the NVME drive as it currently does! My question is if I can do that directly (flash SD, boot from it, and change boot to NVME) and I will have all the previous data on the NVME *OR* should I backup all the data in the NVME format the drive, and then restore the files I care about after reflashing? Thanks in advance!
