https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D229852 Niels Bakker <niels=3Dfreebsd@bakker.net> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |niels=3Dfreebsd@bakker.net --- Comment #1 from Niels Bakker <niels=3Dfreebsd@bakker.net> --- I ran into this issue (on an Intel Celeron 3865U) with the exact symptoms described in the linked thread, and the patch resolved it for me as well. I had tried the other workaround before - only pick devices on another PCI = bus and IRQ line for passthru - but that did not help. Without this patch, any attempt to use a passthru device immediately crashes the whole computer by rendering all PCI devices like AHCI and USB controllers absent. --=20 You are receiving this mail because: You are the assignee for the bug.=
