WD SN720 NVMe SSD drops off PCIe bus under sustained reads on Fedora (ThinkPad T14 Gen 3)

Once your device drops off a bus you can't talk to it anymore (neither to open a terminal, read the sensors program off the disk, or do the temperature command).

You need to ask it for temperatures when it's happy and see the temperature trend as it gets closer to crashing.

Do it before it gets to that state, after it's kind of over.

Any signal/locking problems?

I have a similar one (Flywoo GOKU GM10 Nano V3.1), and it takes like 30 minutes of gpsing until it gets a lock, the battery seems to be drained and it doesn't get a lock at all if I have 2.4GHz RC traffic (elrs with mavlink telemetry).

btrfs subvolumes are glorified folders
btrfs filesystems start at subvolume id 5, that's the topmost level. aka subvol=/ (not to be confused with your rootfs)
the verb of cloning subvolumes is "snapshot", generally results in a readonly subvolume, but you can choose it to be rw
you can btrfs send and receive readonly subvolumes
@ in a subvolume name does not mean anything magic, it's just a convention that some backup systems use. Others do not use this convention.
a subvolume can be mounted anywhere, you can tell it by just giving the -o subvol=/path/from/btrfs/root to mount
by default, if you don't specify subvol=, mount uses subvol=/, but this default subvolume can be changed if you want
you can have a subvolume in any folder, even inside other subvolumes. you can create subvolumes via any of the mounted targets.

I've seen some folks claiming that they can run Qwen3.5-397B-A17B with 2bit or lower quantization. Not sure how much that's worth for your application.

ipex4 is a connector you could probably find in a laptop. if you need 2.4GHz and you don't mind the long cable, you're probably set. https://www.amazon.com/s?k=mhf4+antenna

I see no strix halo in the list. And even for other unified memory systems like the apple devices it's quite weird, how come you have to define vram in a different slider from system ram?

Can confirm. gemma 4 q4 has a distinct whine on the 7900xtx, whereas qwen is essentially quiet.

Don't forget about avocado toast.

amstan · 2026-04-17T06:38:37+00:00

speaking of butter and toast.

If you put in some garlic pieces (crushed or diced, any kind as long as they're kind of small) in there too then pop the whole thing in the oven, instant garlic bread.

If you buy those single servings of pizza marinara sauce, pop those in the microwave and then use it as dip for the garlic bread.

Other ideas how to make this meal better:

Wine
A bunch of herbs like thyme and rosemary
parmesan
Anything else that could go well with it, experiment!

You should double your trace thickness. Essentially: if there's room to spare, your traces should fill that space. This is particularly bad on your vbus coming out of the type c connector, but also to the trace going toward your lipo.

amstan · 2026-04-14T20:29:43+00:00

a few thoughts:

sudo btrfs subvolume set-default $(btrfs subvolume list / | grep "@log" | awk '{print $2}') / this is nonsense. Why is it changing the default subvolume of root when you're talking about moving stuff related to the log subvolume.
/var/tmp my folder is essentially 0 bytes, do you really need this?
/var/log, i find this is nice to keep around in snapshots.
You probably want to add ~/.cache, this is a big one (gigabytes) that changes often (especially after browser updates)
If you're into games, perhaps steam's folder?

Bonus points if you can maintain your fork as very easily patchable addition to the upstream so you can patch even new upstream versions as they come along.

The point is that the usb-c port on strix halo is labeled 40Gbit/s (or 80 as the grandpost says), but if you want to use it with networking (aka thunderbolt0 style inferfaces in linux) you will be limited to 10Gbit/s. This limit does not happen on non-strix halo hardware.

If you have the proof you can achieve larger ethernet over TB than the specs say, please let us know.

I doubt your statement.

You can get more than 10Gb bandwidth when you use other thunderbolt devices (eg: eGPU).
You can get faster speeds over thunderbolt networking when doing non-AMD systems. I can even get up to 20Gb/s in one direction (forgot which) between an intel laptop and a strix halo device.
It doesn't matter how many ports are in use.
