I suffered same issue after upgrade kernel.
When system boots up with SMT enabled, all good in default kernel (5.15.0-43-generic).
But error message occurred after upgrade kernel to 6.2.0.
core 192 reported as disabled
Attempt to enable it fails, resulting the following messages in dmesg:
[ 342.156946] smpboot: Booting Node 0 Processor 192 APIC 0x1
[ 352.156658] smpboot: do_boot_cpu failed(-1) to wakeup CPU#192
