Hello,

I now have 6 of these boards. They are connected to rPi4b/4G with the supplied jumper and have Samsung 860 EVO 1TB SSD's in them.

Two appear to work fine, but the other 4 keep logging :

[Thu Oct 31 15:46:02 2019] sd 0:0:0:0: [sda] tag#20 uas_eh_abort_handler 0 uas-tag 1 inflight: CMD OUT [Thu Oct 31 15:46:02 2019] sd 0:0:0:0: [sda] tag#20 CDB: opcode=0x2a 2a 00 00 cb 0c 5e 00 00 08 00

at random intervals in syslog, accompanied by freezes of the system as I/O is blocked.

I've swapped the SSD's around between working and non working cards, but the problem stays with the non-woring one.

I'm trying to build a HPC cluster here, and this is really letting me down.

Orders 2019-1702, 2019-1891, 2019-2032.

The 2 cards from 2019-1702 appear to be working fine.
