Parsing ELF... No relocation needed... done. Booting the kernel (entry_offset: 0x00000000). After some minutes they reboot. I bisected this down to commit bebb5af001dc6cb4f505bb21c4d5e2efbdc112e2 Author: Thomas Gleixner Date: Fri Mar 22 19:56:39 2024 +0100 x86/mpparse: Register APIC address only once [ Upstream commit f2208aa12c27bfada3c15c550c03ca81d42dcac2 ] The APIC address is registered twice. First during the early detection and afterwards when actually scanning the table for APIC IDs. The APIC and topology core warn about the second attempt. Restrict it to the early detection call.
