I don't even need to attach it: boot freebsd, enter acpi s3, wake up, and then plug in the disk leads to the same problem. i have found out that compiling XHCI has loadable module, and unloading it before suspend and re-loading it afterwards solves the problem. the "xhci_interrupt: host controller halted"-messages don't appear, and i can use my harddisk afterwards. looks like xhci is failing to reinitalize properly after suspend? greetings, flo
