I'm getting a lot of "acpi_spmc0: Unknown revision" messages from this driver on my box, below is the full (non-verbose) boot log. However the affect of those messages is not clear to me. Does it mean S0ix won't work? Or are those just warning messages? The logged text and occurrence of those should be adjusted, it's too verbose right now and the printed message doesn't help the user figure out what's going on. Thanks, Roger. --- EFI framebuffer information: addr, size 0x0, 0x0 dimensions 0 x 0 stride 0 masks 0x00000000, 0x00000000, 0x00000000, 0x00000000 Timeout initializing vt_vga GDB: no debug ports present KDB: debugger backends: ddb KDB: current backend: ddb ---<<BOOT>>--- Copyright (c) 1992-2026 The FreeBSD Project.
