>Originator: Benny Siegert
>Release: NetBSD 9.99.76
>Organization:
The NetBSD Foundation
>Environment:
NetBSD 9.99.76 kernel (since update to 9.99.77) + NetBSD 9 userland, Pinebook Pro, evbarm-aarch64
>Description:
I added an NVMe drive to the Pinebook Pro and created a GPT with some partitions on it (root, EFI, swap, home). The kernel is loaded from eMMC but the root FS is on the NVMe.
Trying to build a Rust program using MAKE_JOBS=6 (thus, highly parallel, using all cores), I can make the machine crash after several minutes of such activity.
gdb is responsive but "sync" hangs for obvious reasons.
Here are two photos I snapped of the backtraces:
https://photos.app.goo.gl/f58UfkoURGxTjF3j8
https://photos.app.goo.gl/JF25NDTEDYK4Uvt26
The backtraces are a little different but both of them are in writes to the file system (below dofilewrite).
>How-To-Repeat:
- aarch64 system (Pinebook Pro)
- root FS on NVME, FFS on GPT
- build some Rust program (in my case, wip/sccache, which is not committed yet).

not that i have any particular insight to the crash (the images
don't show the panic message -- can you get a copy of those?
from ddb, 'dmesg' should show it all with a pager), and we
should figure out what is crashing here, but i do not recommend
using MAKE_JOBS=6 or -j6 on the PBP.
there are two serious issues:
- 3.875GiB of ram vs 6 jobs is simply not enough for many
modern packges. some use >1GiB each.
- the PBP battery controller setup is not the best. it can only
charge at 15W. however, the SoC and devices are quite capable
of using more than 15W, so the battery will drain, even while
plugged into barrel or usb-c power.
i strongly recommend using no more than 3 concurrent jobs.

I went to download these for posterity, but got html blobs back. Can
you post the real urls?
(or just email me the pictures if you like)

Subject: re: port-arm/55922: Kernel panics with nvme+gpt on Pinebook Pro
Date: Tue, 07 Sep 2021 05:58:22 +1000
what's the nvme ssd installed? there are known issues with
many mid-range to high-end ssds in pbp, due to power supply
issues. see this for info about known good bad:
https://wiki.pine64.org/wiki/Pinebook_Pro_Hardware_Accessory_Compatibil=
ity#NVMe_SSD_drives
but also know that all the samsung drives *i* tried did not
work in the end (this table lists 970 PRO as working, and
maybe it does work at PS2 setting.)
you can (should) set the nvme power level to PS2 if you can,
using nvmectl:
nvmectl power -p 2 nvme0
now that i've become more familiar with this failure mode,
i'm some what convinced this PR is a hardware issue and
we can't solve it in software. the mutex spinout happened
because the hardware stopped answering.
it's also possible that even with nvme set to ~2W that
also having the system run -j6 for a long time -- which
does drain the battery normally -- will lead to a case
where the battery can't supply power to the nvme and it
can fail, even with "good low power" nvmes. i have intel
660p's in use, and while mostly it can run down on power
OK, sometimes it will hang IOs and need a reset.
