OpenBSD Errata: January 17th, 2020 (inteldrmctx)
15 January, 2020 by firstname.lastname@example.org | openbsd
Errata patches for the kernel have been released for OpenBSD 6.5 and 6.6. Execution Unit state was not cleared on context switch with Intel Gen9 graphics hardware. Binary updates for the amd64 and i386 platforms are available via the syspatch utility. Source code patches can be found on the respective errata page: https://www.openbsd.org/errata65.html https://www.openbsd.org/errata66.html As these affect the kernel, a reboot will be needed after patching.
