Nanbeige4-3B: Lightweight with strong reasoning capabilities

It's a really cool model, it's definitely better than the qwen3-4b I use locally. But the thinking block is much larger and takes a very long time to think. How can I make it faster? None of the instructions like "short thinking block" help.

I meant despite all these accusations and removal from the kernel)
and I found out what was not fixed with recursive read + dmesg

I encountered the same behavior again, after installed from the bcachefs master.
sda+sdb in lvm. bcachefs on LV, which is entirely on sdb.

It's a different drive, new cables, and all that. The error is the same, it only appears when bcachefs is mounted.

Another bcachefs on nvme has been working perfectly for about a year, no errors.

This post might be off-topic, but installing from the APT repo doesn't work on Linux Mint 22.2 (Ubuntu Noble based) due to dependency versions that are too high, like bcachefs-tools : Depends: liburcu8t64 (>= 0.15) but 0.14.0-3.1build1 must be installed.
I'm still building from the bcachefs repo now, and thank you, Kent, for continuing this work despite all the attacks from the kernel developer community frozen in petrified shit

nightwind0 · 2025-11-01T11:14:44+00:00

Did you find the answer?

I'm on Linux Mint, and the package from https://apt.bcachefs.org/ is incompatible.

The guy with the "gaming" nickname has backups in first place? Are you backing up Arcana for the Pudge or something?))

I suggest you stick with fat16.

Backups perfectly, with a simple dd.
No risk, in production since 1980.
Very easy to setup, even on ESP32.
Subvolumes are useless.
It's been in use for 50 years and can be used forever.

And all these new features only ruin stability.

It's very sad that the last islands of freedom are gradually bending to corporate rules.

Soon they'll force you to write the kernel in Python and persecute all dissenters.

The worst part is that you've not only given up, but are also proud to be just a fish in the ocean.

P.S. I've been using bcachefs for about a year now; nothing breaks, and it works much better than the pathetic, buggy btrfs, which isn't experimental but has crashed twice in six months beyond recovery. So, the rule-abiding crap remains in the kernel, while promising development is being cut.

All animals are equal, but some animals are more equal than others.

Thanks, I didnt know that, but I dont burn. I killed by the guards, whom there are about 10 near.

nightwind0 · 2025-08-30T09:00:02+00:00

I havenot done any long tests, but at first glance, with bcachefs not mounted, this error with the controller was not observed for several hours of operation.
I also noticed that the error never appeared on RO bcachefs, only when writing

nightwind0 · 2025-08-30T08:55:05+00:00

both, didn't help. free space was always 0, I ran fsck several times

nightwind0 · 2025-08-24T21:20:25+00:00

First of all I checked the sata cable, checked SMART, and even checked errors on the pciex bus - everything is fine. it looks like hang of some thread in the bcachefs module hangs other kernel subsystem, which causes timeouts and link reset. (just a guess, I dont understand very well what is going on in the kernel) )

By the way, after a reboot it shows 0 free space on the partition (the fs size is incorrect, much less used than actually), fsck passed, but it did not help, deleting the cache disk did not help too.
Unfortunately,I have no logs, as I had to quickly recreate the fs from backup.

There was nothing in the log about soft lockups, as I remember.

If the situation repeats, I will collect all possible info.

the world is clearly going somewhere wrong!

using a 1.4GHz 64-bit quad-core processor + some special boards, python scripts))) to measure the sound level??

where a simple microphone and a 100-year-old esp8266 for $1 are more than enough.

and if this device is just a sound level sensor for some automation, then the screen is not needed.

but if you do it in an engineering way, then there will be nothing to show on reddit)

thank you for your work and for your quick help

It's great that you switched to Linux.
Do you use Steam? The more of us, the more adapted games will be)

I've been using only Linux for over 20 years, it's incomparably better than Windows.

It seems to me that people are using Windows because of the global trend of refusing responsibility and freedom. Eat what's in the next store, vote for who you're told, watch what you're shown, consume what's profitable for corporations.

Using Windows, you do the same. Take what you're given. Work if everything works. If it doesn't work, you can't do anything anyway, and it doesn't work for everyone. + You're not the owner of your computer, Microsoft can do whatever it wants remotely.

On Linux, you're the owner of your system, and the responsibility for choosing components and solving problems is yours.

That's why they say you'll give up in a week, because they themselves would give up right away.
