https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=291461 --- Comment #7 from Warner Losh <imp@FreeBSD.org> --- maybe this is a duplicate of 292206 which was fixed in: commit d82698ac68c23d856716dc9f6524b9ef363d7eba Author: Jarmo Jaakkola <jarmo.jaakkola@roskakori.fi> Date: Wed Jan 7 22:14:56 2026 -0700 loader.efi: Only use SPCR if enabled. SerialPort in the SPCR is zeroed when serial redirection is disabled, rather than the SPCR being omitted from the ACPI tables ony many systems. Check to see that SerialPort.Address is non-zero before using. FreeBSD would fail to boot on systems that could have a serial port redireciton, but don't have it enabled because the loader would create a bogus hw.uart.console. While one could unset this value to boot, you couldn't do that automatically very easily. Instead, don't even look at the SPCR table if the SerialPort is zero'd. PR: 292206 MFC After: 3 days Sponsored by: Netflix Co-authored-by: Warner Losh <imp@FreeBSD.org> Closes: https://github.com/freebsd/freebsd-src/pull/1948 Maybe cherry-pick to stable/15 and/or releng/15.0 and rebuild loader.efi and see if that restores functionality. -- You are receiving this mail because: You are the assignee for the bug.home | help
