Are there old kernels available?

Basically because the new kernel on my nanopc-t4 has a compatibility glitch with the nvme ssd, but the 4.19 kernel doesn’t seem to have this glitch.

So I want to try the old kernel.

Look for it in the “Manjaro Settings Manager” application.
You should be able to find it there, and you can then install it.
It’s available in the default Manjaro release, I don’t have an ARM processor, so don’t know if it’s available for ARM or not :man_shrugging:
I think it is though:

I think he’s referring to:

To be precise I didn’t find Linux419 in the Manjaro ARM repositories. :smiling_face_with_tear:

Hey @YoungFellow
Thank you for the reply but this is not right for ARM processors.

Currently only 1 kernel can be installed and used on arm as we do not have grub and uefi support yet.

Currently we only Maintain the latest LTS kernel and the RC kernel on arm project.
If you’re comparing Linux-4.19 from vendor then that is a BSP kernel and not mainline kernel.

Please check the difference between BSP and Mainline kernel on internet search as it is out of scope for this thread.

If you can share more about this issue then maybe I can look into it and see why it does not work as it works on BSP Kernel.

Regards,

Sounds interesting.

Also is there a way to make the kernel print more logs? There doesn’t seem to be much valuable information.

https://bugzilla.kernel.org/show_bug.cgi?id=216009
I have reported this glitch.

Kindly follow this first.

Kernel.org team might not respond to your bug cause it does not belong to mainline kernel.
Someone have to write drivers in mainline to make it work. Comparing Apple/BSP kernel to Mango/mainline kernel is not right.

Also comparing Manjaro X86 with Manjaro ARM is not right, please try to ready more about the architectural difference.

It would be better if you can explain the real issue here in details.

I really can’t seem to get any more useful logs. :neutral_face:

I am not asking about logs.
I am asking about what works on 5.17 and what does not work.

Please share.

PCIE node is already present so I expect PCIE slot to work fine

Hey @Dark_iaji

Can you add this to the extlinux.conf file inside /boot/extlinux
earlycon in this line
console=ttyS2,1500000 root=PARTUUID=dcee78f5-50ba-42e0-b267-8179689bc7a4 rw rootwait audit=0 splash plymouth.ignore-serial-consoles

Like this
console=ttyS2,1500000 root=PARTUUID=dcee78f5-50ba-42e0-b267-8179689bc7a4 rw rootwait audit=0 earlycon splash plymouth.ignore-serial-consoles

With this you will get better logs.
Also which NVMe are you using ?

Samsung’s OEM SSD PM981a, this SSD works fine, and ZhiTai TiPlus5000, this SSD has a system freeze failure.

Oh dear. Now you explain the real issue.
ZhiTai TiPlus5000 sounds like unbranded NVMe and there is no detail about it on internet so I doubt any linux kernel developer would ever work on it.

Maybe you need to find more about this drive and share the details so maybe we can enable the required function for it or maybe it is just not very much supported on arm architecture.

Zhitai is basically the own brand of ymtc, a flash memory manufacturer.
The flash memory of ymtc is characterized in that the rewritable number of times is twice or even several times higher than that of Samsung’s flash memory.

Nice so maybe you should report it to ymtc so they can look into linux drivers and patch it as needed.

I have actually reported the failure to the manufacturer of the SSD. :neutral_face:

But I don’t think they’re going to spend more on such a niche segment, so this glitch might be a low priority.

Earlier, I reported that they took up the PCI ID of 1cc1, which belongs to ADATA, and they still haven’t replied to me. :neutral_face:

The additional earlycon kernel parameter doesn’t seem to provide much more logging. :neutral_face:

The UART’s kernel log timestamps seem to indicate that the kernel has become very slow. :face_with_monocle:

Yes I had similar issue before with Lexar NVMe then I switched on Kingston A1000 NVMe.

So from the above explanation, I understand that ZhiTai TiPlus5000 is a replica of ADATA drive and ADATA already have bad driver support in Linux.

And that’s sad.

I have learned that for data storage also go with the known brands like Sandisk, Kingston, Transcend, Samsung and Crucial.

In my experience using SSD production tools, usually if you don’t modify the ID of its device manufacturer, usually the default setting will have a default ID, which may be why it is 1cc1, but the kernel parameters can modify this ID ? This may load a more correct driver.

In fact, the reason for choosing TiPLUS5000 is that its flash memory reliability has been proved by the miners who mine Chia coins in the past. Basically, the number of times of erasing and writing can be comparable to the past 2DMLC, and the 1TB PC005 can reach 1000TB or even higher write volume. Samsung’s 970 EVO PLUS typically runs out of flash life before reaching this write volume, while the PC005 uses ymtc’s outdated 64-layer stacked V-NAND, and the TiPLUS5000 is a state-of-the-art 128-layer stacked V-NAND, theoretically It will only be better, and from the evaluation point of view, the read and write performance of TiPLUS5000 is good, and the biggest highlight is that its power consumption is very low, almost tied for the best with Hynix P31. The low-temperature SSD has excellent performance and the highest reliability. This is the reason why I choose to use this SSD on the ram development board.

Then why did @Strit use the plural tense?
Perhaps a mistake?

No.

Cause we so have multiple kernels and they’re more About arm soc variant based then like upstream version based.
Example
linux-lts
linux-rc
linux-khadas
linux-odroid

And many more.

Okay, thanks for the info @spikerguy

You’re welcome :smiley:
