Hi, Following daily snapshots, I have hit a bug that was introduced between 6.5-current #61 and 6.5-current #66 (not sure if it was related to the LLVM upgrade).
Reference system is bhyve on FreeBSD 11.2 with an OpenBSD guest. #61 boots fine and runs as expected. However, #66 get to the following point and the guest terminates: scsibus0 at mpath0: 256 targets mainbus0 at root bios0 at mainbus0: SMBIOS rev. 3.0 @ 0xbf957000 (11 entries) bios0: vendor BHYVE version "1.00" date 03/14/2014 bios0: bhyve BHYVE acpi0 at bios0: ACPI 4.0 acpi0: sleep states S5 acpi0: tables DSDT FACP HPET APIC MCFG SPCR acpi0: wakeup devices acpitimer0 at acpi0: 3579545 Hz, 32 bits acpihpet0 at acpi0: 16777216 Hz acpimadt0 at acpi0 addr 0xfee00000: PC-AT compat cpu0 at mainbus0: apid 0 (boot processor) cpu0: Intel(R) Xeon(R) CPU E3-1230 v6 @ 3.50GHz, 3504.21 MHz, 06-9e-09 cpu0: FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,CFLUSH,MMX,FXSR,SSE,SSE2,SS,HTT,PBE,SSE3,PCLMUL,DTES64,DS-CPL,SSSE3,SDBG,FMA3,CX16,xTPR,PCID,SSE4.1,SSE4.2,MOVBE,POPCNT,AES,XSAVE,AVX,F16C,RDRAND,HV,NXE,PAGE1GB,LONG,LAHF,ABM,3DNOWP,ITSC,FSGSBASE,BMI1,HLE,AVX2,BMI2,ERMS,INVPCID,RTM,ARAT,XSAVEOPT,MELTDOWN cpu0: 256KB 64b/line 8-way L2 cache cpu0: smt 0, core 0, package 0 mtrr: CPU supports MTRRs but not enabled by BIOS (Note: The above was text from #61 but was all the console text (as UEFI is graphics) I could copy/paste).

Please advise if there is any further information that is needed. Jason.
