I got one on my hands as of yesterday, I played around with OPi provided Ubuntu server image, but it is terrible. I would love to start working on support for this board as for me it looks as quite interesting option. Wireless chip there reports 2(!) bands and AP+managed mode combination, which means I can use it as Wi-Fi extender and other nice things.

Actually nevermind, the seller exchanged the cable and it all works now. IO kills CPU though....

As Igor noted this is hardly has anything to do with Armbian specifically. This is more Linux specific (and if you did not have any problems on other custom images does not really mean anything) most linux systems would come by default with apparmor (in case of Ubuntu) or selinux (in case of RHEL based systems) and iptables. Either of those may prevent you from getting your ports accessed. iptables would block port access on linux kernel level (namely tcp/ip stack) and apparmor/selinux would not allow application to obtain the port unless explicitly permitted (not sure about apparmor as never used it really). As there is not much info in your post you would either check if those are installed/enabled and give this info here and perhaps also check on https://unix.stackexchange.com/ which is more relevant place for troubleshooting this IMO.

So I've got this 88SE9215 based board that is similar to the ones already posted except that it uses single SAS port instead of x4 SATA ports. The board comes with a splitter cable 1 SAS to 4 SATA + LED head. The cable is completely compatible with the board as the seller claims. I will attach pictures below. The board is detected (as per below), but if I attach disks they do not show up in the system at all. dmesg has no new messages and the disk is shutdown after 20-30 seconds (parks head and stops the motor) with lsscsi showing nada. Any thoughts on why I cant get it work? Now when I plug this board and boot, from `dmesg | grep ata` I get 4 new SATA devices detected: root@espressobin:~# dmesg | grep ata [ 0.000000] Memory: 1000200K/1048576K available (10236K kernel code, 714K rwdata, 3184K rodata, 576K init, 552K bss, 31992K reserved, 16384K cma-reserved) [ 0.000000] .rodata : 0xffffff8008a80000 - 0xffffff8008da0000 ( 3200 KB) [ 0.000000] .data : 0xffffff8008e30000 - 0xffffff8008ee2a00 ( 715 KB) [ 0.420045] vdso: 2 pages (1 code @ ffffff8008a86000, 1 data @ ffffff8008e35000) [ 1.671420] libata version 3.00 loaded.
