Just checked, a standard 1.1.3 build behaves identically to both the official 1.1.1 binary and my 1.1.3 CONFIG_PAYLOAD_SEABIOS=y build. (And, since I now have an EFI build again with which...
memtest86 (the PassMark one, version 7.3) fully passes, FreeBSD, OpenBSD, and 9front (!) all work. NetBSD and [bunnix](https://git.sr.ht/~sircmpwn/bunnix) cause the same freeze-then-reboot as Linux. I would check Windows, but I...
Full order of flashes: - 1.1.1, using DTS. Disabled ME, unfortunately before checking if it froze, since I didn't expect to have issues past the bootloader - SeaBIOS 1.1.3, using...
Aha! Found a suspicious entry in the FreeBSD dmesg (`MADT: Ignoring local APIC ID 387323156 (too high)`), and turns out adding `nolapic` to the Linux command line fixes the freeze....
cbmem: https://p.d2evs.net/EvYC~E~M8vDtE.txt dmesg (Alpine 3.20 extended, with `maxcpus=7`): https://p.d2evs.net/HOoTgVTGn5UFM.txt I investigated a bit more, and found that `maxcpus=7` (without `nolapic`) also fixes the freeze, and is (I think) less invasive...
Built the dasharo-4.21 branch (which has that patch), partial success. Linux still freezes without `maxcpus=7`, though now substantially earlier in the boot - around 2s in, judging by the kernel...
Telling Grub to use the stock BIOS's DSDT fixes the freeze as well. Since it might be relevant, the output of `acpidump` under dasharo-4.21 is https://p.d2evs.net/K0ds6Yi3QBd5b.txt. I can share the...
Freeze also happens on booting with maxcpus=7 then hotplugging the 8th core (cpu7) after boot, which makes setting up netconsole much easier. dmesg logs (with acpi.debug_level and acpi.debug_layer both set...
