December 1, 20196 yr Everything has been running fine on 6.4.3 for 2+ years now. When I try and upgrade, the drives running off the external sata card disappear. I have removed all of the Dynamix plugins as previously suggested. Meant 6.8.0rc7 not rc8. Logs for 6.4.3 tower-diagnostics-20191130-2125.zip Edited December 1, 20196 yr by erichner
December 1, 20196 yr 04:00.0 SATA controller [0106]: Marvell Technology Group Ltd. 88SE9230 PCIe SATA 6Gb/s Controller [1b4b:9230] (rev 11) Marvel based controllers haven't been recommended for a while now. They suffer from exactly what you are seeing (random drops etc). If you're not running any VM's with passthrough, you may see some improvement by disabling IOMMU (vt-d) in the BIOS. The recommended cards are LSI based.
December 1, 20196 yr Community Expert This workaround works for some, but like mentioned best bet would be getting rid of the Marvell controller.
