I have just upgraded to kernel 5.19.7-1.1 from the tumbleweed repo. I can boot the system. I still get these usci_acpi related error messages in the boot log: Sep 08 22:08:11 localhost kernel: ucsi_acpi USBC000:00: UCSI_GET_PDOS failed (-95) Sep 08 22:08:13 localhost.localdomain kernel: ucsi_acpi USBC000:00: con2: failed to register alt modes Sep 08 22:08:13 localhost.localdomain kernel: ucsi_acpi USBC000:00: PPM init failed (-110) But no longer the Null pointer exceptions.
