Hi . This may seem a little strange but here goes . I am running older hardware and am getting . ata1: softreset failed (device not ready) ata3: softreset failed (device not ready) ata2: softreset failed (device not ready) I have read that sata-pmp is the culprit is it possible to disable this from the boot cmdline or is it a kernel rebuild the motherboard has an AMD chipset 00:05.0 PCI bridge: Advanced Micro Devices, Inc. [AMD/ATI] RS690 PCI to PCI Bridge (PCI Express Port 1) 00:11.0 SATA controller: Advanced Micro Devices, Inc. [AMD/ATI] SB7x0/SB8x0/SB9x0 SATA Controller [IDE mode] kernel 4.8.3-1-ARCH #1 SMP PREEMPT Thu Oct 20 19:53:59 CEST 2016 x86_64 GNU/Linux 3 Sata drives no SSD devices . Thanks pete .
