[rmk-arm:aarch64/hotplug-vcpu/v6.6-rc1] [ACPI] 9d0b332731: Kernel panic - not syncing: Fatal exception

[kernel test robot]

Hello,

kernel test robot noticed "Kernel panic - not syncing: Fatal exception" on:

commit: 9d0b33273119d6c0d9112a28c2cc2eb8c671fbeb ("ACPI: processor: Register all CPUs from acpi_processor_get_info()")
git://git.armlinux.org.uk/~rmk/linux-arm aarch64/hotplug-vcpu/v6.6-rc1

in testcase: boot

compiler: gcc-12
test machine: 96 threads 2 sockets Intel(R) Xeon(R) Gold 6252 CPU @ 2.10GHz (Cascade Lake) with 512G memory

(please refer to attached dmesg/kmsg for entire log/backtrace)



If you fix the issue in a separate patch/commit (i.e. not just a new version of
the same patch/commit), kindly add following tags
| Reported-by: kernel test robot <oliver.sang@xxxxxxxxx>
| Closes: https://lore.kernel.org/oe-lkp/202310111516.ba5ea8dc-oliver.sang@xxxxxxxxx
