Sorry, the dmesg included in my report was not from the affected machine. The below is the correct dmesg for the system where the em0 issue happened: dmesg: OpenBSD 6.7-current (GENERIC.MP) #186: Thu May 14 00:13:53 MDT 2020 dera...@amd64.openbsd.org:/usr/src/sys/arch/amd64/compile/GENERIC.MP real mem = 16872108032 (16090MB) avail mem = 16348143616 (15590MB) mpath0 at root scsibus0 at mpath0: 256 targets mainbus0 at root bios0 at mainbus0: SMBIOS rev. 2.7 @ 0xdae9d000 (71 entries) bios0: vendor LENOVO version "G2ET33WW (1.13 )" date 07/24/2012 bios0: LENOVO 23252FG acpi0 at bios0: ACPI 4.0 acpi0: sleep states S0 S3 S4 S5 acpi0: tables DSDT FACP SLIC TCPA SSDT SSDT SSDT HPET APIC MCFG ECDT FPDT ASF!
