@ArmBoy1988 seems You were right: got SK Hynix module, now R/W is almost the same, 400MB/s (not so bad, remembering that OPi has PCIe Gen2). Will test also with encrypted partition.

Providing logs with armbianmonitor -u helps with troubleshooting and significantly raises chances that issue gets addressed.

This is highly expected. We don't even try to support EDGE kernels at end user level. This kernel is EOL and will be replaced with a v6.12.y in next year Q1 release. But we can't secure you that this problem will be fixed as support budget is negative (we have some support for other boards from Radxa) and we, nobody in the team, can't afford to spent days or weeks resolving this. However, you are welcome to spent at least time and join debugging this - problems is as yours as it is ours. The reasons why we keep build framework in a good state is that you can help resolving problems https://github.com/armbian/build We are and will always be too small to face this mountain of problems that are generated by everyone, compensated by no-one. Not by us, but all community that is poking kernels, and hardware dealers that are flooding this market.

Warning: GPT-partitioned Armbian images are appearing in the wild, and the script and tutorial do not support such images yet. To check whether your image is GPT-partitioned, run /sbin/fdisk -l on the unzipped image file. If you see 'dos' reported as the disklabel type, you're OK, while if you see 'gpt', you're out of luck for now.

Hi, I'm using Armbian Bookworm for my Orangepi 4 LTS (RK3399). In the setting section (Armbian-config), I did enable SPI, however after rebooting, there is no spidev in the /dev/ directory. I hope you can help me. Also I need usart2B, I know its pins are available in this board but I don't see any related configuration or options.
