The situation is the same with the kernel from archlinuxarm, even though it only runs at 800 MHz: http://ix.io/1JH2

I just tried building and booting Linux 5.1.0-g72cf0b074 directly from torvalds/linux.git. It boots fine, but after some time, it crashes with the same kind of errors as the Armbian kernel. Here is one of them: http://ix.io/1JH1

Here is an update: I just tried replacing the kernel with 4.4.8-armada-17.02-espressobin downloaded from http://espressobin.net/tech-spec/ I put the "Image" file at "/boot/Image", and the "armada-3720-community.dtb" at "/boot/dtb/marvell/armada-3720-community.dtb". Now everything seems fine. I haven't seen any crashes at all so far, and rebooting works fine. root@espressobin:~# uname -a Linux espressobin 4.4.8-armada-17.02.2-g8148be9 #8 SMP PREEMPT Wed Jul 4 11:59:53 UTC 2018 aarch64 GNU/Linux root@espressobin:~# 7za b 7-Zip (a) [64] 16.02 : Copyright (c) 1999-2016 Igor Pavlov : 2016-05-21 p7zip Version 16.02 (locale=en_US.UTF-8,Utf16=on,HugeFiles=on,64 bits,2 CPUs LE) LE CPU Freq: 997 997 998 998 997 998 995 996 RAM size: 930 MB, # CPU hardware threads: 2 RAM usage: 441 MB, # Benchmark threads: 2 Compressing | Decompressing Dict Speed Usage R/U Rating | Speed Usage R/U Rating KiB/s % MIPS MIPS | KiB/s % MIPS MIPS 22: 868 152 555 844 | 22465 199 962 1918 23: 859 153 574 876 | 22076 199 958 1911 24: 853 153 599 918 | 21731 200 955 1908 25: 848 153 632 968 | 21340 199 953 1899 ---------------------------------- | ------------------------------ Avr: 153 590 902 | 199 957 1909 This is probably a stupid question, but why don't we just apply the patches from https://github.com/MarvellEmbeddedProcessors/linux-marvell/tree/linux-4.4.8-armada-17.02-espressobin to the 4.19.20 kernel used by Armbian? What is the current state of that work? Can I help out?

Hi All! I am having a lot of trouble making my ESPRESSObin v7 1GB DDR4 run without crashes. I have tried both Bionic (5.75 4.19.20) and Stretch (5.75 4.19.20) images, and neither are stable. I have tried with a lot of different PSUs (all switch-mode though) and booting from both microSD and USB sticks. My U-Boot is "flash-image-ddr4-1g-1cs-1000_800.bin". It seems like there is about 50% chance that it will boot without a crash. The type of crashes I get seems random. Ex http://ix.io/1JGY And then it just freezes. Or this one which includes a proper kernel Oops: http://ix.io/1JGZ While running, I get errors like this one: [ 71.136812] BUG: Bad page state in process khugepaged pfn:31d99 [ 71.140206] page:ffffffbf00c76640 count:0 mapcount:0 mapping:0000000000002000 index:0x0 [ 71.148428] flags: 0x0() [ 71.151049] raw: 0000000000000000 0000000000000000 ffffffbf00c76648 0000000000002000 [ 71.159015] raw: 0000000000000000 0000000000000000 00000000ffffffff 0000000000000000 [ 71.166975] page dumped because: non-NULL mapping [ 71.172329] BUG: Bad page state in process khugepaged pfn:3261c [ 71.178001] page:ffffffbf00c98700 count:0 mapcount:0 mapping:0000000000002000 index:0x0 [ 71.186236] flags: 0x0() [ 71.188853] raw: 0000000000000000 0000000000000000 ffffffbf00c98708 0000000000002000 [ 71.196825] raw: 0000000000000000 0000000000000000 00000000ffffffff 0000000000000000 [ 71.204782] page dumped because: non-NULL mapping Once successfully booted, setting the CPUfreq governor to "performance" seems to make it more stable. Am I the only one having problems getting a stable boot on V7? Has anyone of you any tips on how to make it stable? I am willing to try compiling a new kernel if some experimental patches exists.

Hi Igor How about including "webseeds"/"http seeds" in your .torrent files? You already have a lot of mirrors (ex http://mirrors.dotsrc.org/armbian-dl/), so it would be very helpful if your torrent client could also download from all those mirrors. Spec: http://www.bittorrent.org/beps/bep_0019.html
