For the vendor-rk35xx kernel (6.1.115): an out-of-tree build of the vendor imx415 driver with a real 4K@60 mode, plus the overlay to bind it. https://github.com/bambooCZ/rk3588-imx415-4k60

@foxx1337 If you are interested somebody on Radxa forum has the same opinion. I am not experienced enough with DTOs so maybe he can help you as well https://forum.radxa.com/t/samsung-990-pro-2tb-ssd/20166/6?u=bamboo

I confirm this. But I still think it is not a kernel problem as all (radaxa, joshua, armbian 6.8) behave exactly the same. On my Pi the mark is about 11 GB. I already raised a complaint at Radaxa so wish me luck. Thank you guys, I won't bug you here any more.

I've got another update: the SSD isn't dead. I was just tired and didn't notice that the USB cable fell from USB-A to USB-C adapter. That was the reason it didn't appear on another PC. Then I decided to use the new SSD in my main machine and use my old SSD in Rock Pi. Didn't help. Now I've got two different SSDs which behave the same. This rules out a hardware fault on SSD side. I've tested different filesystems (ext4 and exfat) to rule out a bug in the filesystem implementation. Both behave the same except ext4 has much more consistent performance. Then I installed memtester. And boom. The fault is not caused by NVMe, but rather faulty memory as @foxx1337 suggested. This happens all the time even in big PC world. So I guess that I just wasn't lucky and my Pi has faulty memory. Does this make sense?

Thank you guys, but the SSD is probably dead. I've tried Arch based on 5.10 kernel and after I've started the copy process it crashed as well but this time the SSD doesn't appear on any other PC. So I am going for a service with it. So this might actually be a HW failure. Good thing is that the Pi survived (crossed fingers) and that I won't have to address refund with China.

Hello, I've problem... Message from syslogd@rock-5b at Feb 23 21:58:00 ... kernel:[ 443.674152] Internal error: Oops: 0000000096000004 [#1] PREEMPT SMP Message from syslogd@rock-5b at Feb 23 21:58:00 ... kernel:[ 443.674152] Internal error: Oops: 0000000096000004 [#1] PREEMPT SMP Message from syslogd@rock-5b at Feb 23 21:58:00 ... kernel:[ 443.718480] Code: b40001b3 f1036273 d503201f 54000140 (f9402261) Message from syslogd@rock-5b at Feb 23 21:58:00 ... kernel:[ 443.718480] Code: b40001b3 f1036273 d503201f 54000140 (f9402261) I have exactly zero experience with debugging this. But from my trial-error it will have something to do with NVME as this is the only thing that remains. This error happen after copying data to SSD in M.2 slot. I tried copying USB -> SSD and SFTP -> SSD . Happens everytime after about 5 GB is copied. Configuration: * Rock Pi 5B, 32 GB RAM * SSD: Samsung 990 PRO 2TB * Power Supply: Dummy 12V DC adapter 3A * Up-to-date Armbian with 6.8.0-rc1-edge-rockchip-rk3588 * Latest bootloader in NAND * Boot from NVME The only NOT up-to-date thing is the Samsung firmware. I haven't found a way how to update it inside the Pi. What can I do? Please help.
