It booted with no problems! Any chance this will be a 6.3 Errata? dmesg below. Note, it seems the CPU is different with this t2.medium (Intel(R) Xeon(R) CPU E5-2676 v3 @ 2.40GHz) vs. (Intel(R) Xeon(R) CPU E5-2686 v4 @ 2.30GHz) in my previous report. So I spun up another t2.medium with (Intel(R) Xeon(R) CPU E5-2676 v3 @ 2.40GHz) running 6.3, ran syspatch, and watched it fall all over itself again. So it seems that whatever's in -current fixed the problem. -ME OpenBSD 6.3-current (GENERIC.MP) #144: Thu Jul 26 08:20:44 MDT 2018 dera...@amd64.openbsd.org:/usr/src/sys/arch/amd64/compile/GENERIC.MP real mem = 4278190080 (4080MB) avail mem = 4139360256 (3947MB) mpath0 at root scsibus0 at mpath0: 256 targets mainbus0 at root bios0 at mainbus0: SMBIOS rev. 2.7 @ 0xeb01f (12 entries) bios0: vendor Xen version "4.2.amazon" date 08/24/2006 bios0: Xen HVM domU acpi0 at bios0: rev 2 acpi0: sleep states S3 S4 S5 acpi0: tables DSDT FACP APIC HPET WAET SSDT SSDT acpi0: wakeup devices acpitimer0 at acpi0: 3579545 Hz, 32 bits acpimadt0 at acpi0 addr 0xfee0: PC-AT compat ioapic0 at mainbus0: apid 1 pa 0xfec0, version 11, 48 pins , remapped to apid 1 cpu0 at mainbus0: apid 0 (boot processor) cpu0: Intel(R) Xeon(R) CPU E5-2676 v3 @ 2.40GHz, 2394.85 MHz cpu0: FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,CFLUSH,MMX,FXSR,SSE,SSE2,HTT,SSE3,PCLMUL,SSSE3,FMA3,CX16,PCID,SSE4.1,SSE4.2,MOVBE,POPCNT,DEADLINE,AES,XSAVE,AVX,F16C,RDRAND,HV,NXE,RDTSCP,LONG,LAHF,ABM,FSGSBASE,BMI1,AVX2,SMEP,BMI2,ERMS,INVPCID,XSAVEOPT,MELTDOWN cpu0: 256KB 64b/line 8-way L2 cache cpu0: smt 0, core 0, package 0 mtrr: Pentium Pro MTRR support, 8 var ranges, 88 fixed ranges cpu0: apic clock running at 100MHz cpu1 at mainbus0: apid 2 (application processor) cpu1: Intel(R) Xeon(R) CPU E5-2676 v3 @ 2.40GHz, 2394.88 MHz cpu1: FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,CMOV,PAT,PSE36,CFLUSH,MMX,FXSR,SSE,SSE2,HTT,SSE3,PCLMUL,SSSE3,FMA3,CX16,PCID,SSE4.1,SSE4.2,MOVBE,POPCNT,DEADLINE,AES,XSAVE,AVX,F16C,RDRAND,HV,NXE,RDTSCP,LONG,LAHF,ABM,FSGSBASE,BMI1,AVX2,SMEP,BMI2,ERMS,INVPCID,XSAVEOPT,MELTDOWN cpu1: 256KB 64b/line 8-way L2 cache cpu1: smt 0, core 0, package 1 acpihpet0 at acpi0: 6250 Hz acpiprt0 at acpi0: bus 0 (PCI0) acpicpu0 at acpi0: C1(@1 halt!) acpicpu1 at acpi0: C1(@1 halt!) acpicmos0 at acpi0 "ACPI0007" at acpi0 not configured "ACPI0007" at acpi0 not configured pvbus0 at mainbus0: Xen 4.2 xen0 at pvbus0: features 0x705, 32 grant table frames, event channel 4 xbf0 at xen0 backend 0 channel 6: disk scsibus1 at xbf0: 2 targets sd0 at scsibus1 targ 0 lun 0: SCSI3 0/direct fixed sd0: 8192MB, 512 bytes/sector, 16777216 sectors xnf0 at xen0 backend 0 channel 7: address 02:de:66:59:18:8a "console" at xen0: device/console/0 not configured pci0 at mainbus0 bus 0 pchb0 at pci0 dev 0 function 0 "Intel 82441FX" rev 0x02 pcib0 at pci0 dev 1 function 0 "Intel 82371SB ISA" rev 0x00 pciide0 at pci0 dev 1 function 1 "Intel 82371SB IDE" rev 0x00: DMA, channel 0 wired to compatibility, channel 1 wired to compatibility pciide0: channel 0 disabled (no drives) pciide0: channel 1 disabled (no drives) piixpm0 at pci0 dev 1 function 3 "Intel 82371AB Power" rev 0x01: SMBus disabled vga1 at pci0 dev 2 function 0 "Cirrus Logic CL-GD5446" rev 0x00 wsdisplay0 at vga1 mux 1: console (80x25, vt100 emulation) wsdisplay0: screen 1-5 added (80x25, vt100 emulation) xspd0 at pci0 dev 3 function 0 "XenSource Platform Device" rev 0x01 isa0 at pcib0 isadma0 at isa0 fdc0 at isa0 port 0x3f0/6 irq 6 drq 2 com0 at isa0 port 0x3f8/8 irq 4: ns16550a, 16 byte fifo com0: console pckbc0 at isa0 port 0x60/5 irq 1 irq 12 pckbd0 at pckbc0 (kbd slot) wskbd0 at pckbd0: console keyboard, using wsdisplay0 pms0 at pckbc0 (aux slot) wsmouse0 at pms0 mux 0 pcppi0 at isa0 port 0x61 spkr0 at pcppi0 vscsi0 at root scsibus2 at vscsi0: 256 targets softraid0 at root scsibus3 at softraid0: 256 targets root on sd0a (408f5ba7d26a4b06.a) swap on sd0b dump on sd0b fd0 at fdc0 drive 0: density unknown fd1 at fdc0 drive 1: density unknown
