I use latest bios. Unfortunately it happens only sometimes, so I
cannot try bisect.

your config has
CONFIG_NR_CPUS=2
ACPI MADT said:
[ 0.000000] ACPI: LAPIC (acpi_id[0x00] lapic_id[0x00] enabled)

so it should be ok

maybe you could enable
CONFIG_MTRR_SANITIZER=y
CONFIG_MTRR_SANITIZER_ENABLE_DEFAULT=1
CONFIG_MTRR_SANITIZER_SPARE_REG_NR_DEFAULT=1

I will check latest git, if that reboots still exists.
