Array randomly dropping parity drive before throwing millions of read errors

[Jeebus90]

I have my machine set up for two simultaneous users for myself and my wife, the array will randomly drop the parity throwing millions of errors which disappear on rebooting, there are no smart errors on the drives.

The log file suggests its having trouble connecting to the drive and tries to connect at lower speeds but I don't know what would cause this, I have replaced the cables but it seems like the sata controller just shits the bed.

I have split the IOMMU grouping by enabling ACS override, Ive also run 14 passes of memtest with no errors over a weekend

I have a sata  add in card that uses the JMB585 chipset but this doesnt have any array drives on it, just SSDs for the VMs.

 

Any help would be greatly appreciated.

 

Specs are:

Ryzen 5900X in an asus X470 strix

5700xt + gtx 1060

32gb corsair 3200MHz RAM

corsair ax860W PSU

Here you are, ive had a look through the bios and by default all the sata ports have hotplugging disabled, ive enabled it for all ports but could this be causing the problem?

You'll need to grab a new set after the parity drops again.
