This started with 4.3.0, with 4.3.0-rc7 the system was booting properly (except for the xsave=0 workaround, without that i also get a crash dump right before the APIC error). > >> (XEN) Resetting with ACPI MEMORY or I/O RESET_REG. >> >> I can also see some weird acpi-related messages on the log i attached, like: >> (XEN) ACPI: Invalid sleep control/status register data: 0:0x8:0x3 0:0x8:0x3 >> (XEN) ERST table was not found >> [ 3.608404] ACPI Error: [\_SB_.PCI0.XHC_.RHUB.HS11] Namespace lookup >> failure, AE_NOT_FOUND (20150818/dswload-210) >> [ 3.608410] ACPI Exception: AE_NOT_FOUND, During name lookup/catalog >> (20150818/psobject-227) >> [ 3.608439] ACPI Exception: AE_NOT_FOUND, (SSDT:xh_rvp08) while >> loading table (20150818/tbxfload-193) >> [ 3.619914] ACPI Error: 1 table load failures, 5 successful >> (20150818/tbxfload-214) >> [ 3.679113] [Firmware Bug]: ACPI: BIOS _OSI(Linux) query ignored >> [ 3.688942] ACPI Exception: AE_NOT_FOUND, While evaluating Sleep >> State [\_S1_] (20150818/hwxface-580) >> [ 3.688948] ACPI Exception: AE_NOT_FOUND, While evaluating Sleep >> State [\_S2_] (20150818/hwxface-580) >> [ 3.756027] PM-Timer failed consistency check (0xffffff) - aborting. >> >> With older kernels (like 3.12 or 4.2.1) i always see those messages but >> i'm able to boot without the acpi error. > > I guess those latter messages are unrelated - not the difference > between ACPI and APIC. Also I'm unsure about you saying "boot" > here but "reboot" above? The APIC error prevents me from booting the machine, causing a forced reboot, the above messages won't.

Do you think that this could be caused by some sort of hardware/firmware issue?
