Ho risolto eliminando e, subito dopo, mascherando il kernel 6.18.18. Dopodichè ho aggiornato e mi ha scaricato il kernel 6.12.77. L'ho compilato e non mi ha dato nessun problema. Evidentemente c'è qualcosa che non funziona (bug?) nella versione del kernel 6.18.18.

Magari questa discussione può aiutarti.

Vorrà dire che andrò a spulciarmi il kernel per modificare la voce CXL_ACPI e settarla su "no".

ænigma · Post by **ænigma** » Fri Mar 27, 2026 7:35 pm

Ho ricompilato il kernel 6.18.18 togliendo la flag a CXL_ACPI e la sua compilazione è andata a buon fine.
Grazie mille a fedeliallalinea per il suggerimento.
