Any conclusion? > ... > [1]: https://bugzilla.kernel.org/show_bug.cgi?id=217902 Thanks for the heads-up. I can't tell whether PCI is involved here. The bugzilla only mentions the SATA link, which is on the downstream side of the PCI SATA device. If PCI is involved, e.g., if the PCI core reset the SATA device because of an error, there may be hints in the dmesg log. Can you attach the complete dmesg log and "sudo lspci -vv" output to the bugzillla? Bjorn
