https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D224250 Bug ID: 224250 Summary: Sending SCSI command to ATA device makes kernel triple fault. Product: Base System Version: 10.3-RELEASE Hardware: amd64 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: freebsd-bugs@FreeBSD.org Reporter: claunia@claunia.com When sending a SCSI command thru CAM to an ATA device, kernel triple faults= and machine hangs completely. No crash dump is generated. Code can be found in: https://github.com/claunia/DiscImageChef/blob/7e4ba43063006fe9ef0ab157a7515= 7f573b64db8/DiscImageChef.Devices/FreeBSD/Command.cs#L83 It only happens when csio.data_ptr is set. Setting it using .NET pinned pointers (aka GCHandle), .NET memory allocation (aka AllocHGlobal), or libc memory allocation (aka malloc), makes no difference. Same code with SATA, SCSI or SAS devices work as expected. --=20 You are receiving this mail because: You are the assignee for the bug.=
