https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=236374 Pero Oršolić <bsd@orsolic.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |bsd@orsolic.org --- Comment #1 from Pero Oršolić <bsd@orsolic.org> --- I am also experiencing this issue. I have been using vm-bhyve and PCI passthru for several years now on AMD CPU. I am forwarding multiple LAN, WLAN and USB PCI cards to the various VMs. FreeBSD 14.3-RELEASE, 1 day of uptime, several (less than 10 IIRC) restarts of VM. After few restarts of VM these messages start to appear in the syslog on VM start: ivhd0: Error: completion failed tail:0x570, head:0x20. ivhd0: Dump last 1 command(s): [CMD0, off:0x10] opcode= 0x1 0x28c3eb1 0x0 0xa5a5 ivhd0: Error: completion failed tail:0x620, head:0x20. ivhd0: Dump last 1 command(s): [CMD0, off:0x10] opcode= 0x1 0x28c3eb1 0x0 0xa5a5 ivhd0: Error: completion failed tail:0x6d0, head:0x20. ivhd0: Dump last 1 command(s): [CMD0, off:0x10] opcode= 0x1 0x28c3eb1 0x0 0xa5a5 Inside Linux guest, when passed-through PCI USB card work: Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 001 Device 002: ID 05e3:0610 Genesys Logic, Inc.
