Hi all,
I am having the exact same issue.
linux-lts-6.6.28-1 works, anything above doesnt.
When kernel above linux-lts-6.6.28-1: - Boltctl does not show anything - thunderbolt.host_reset=0 had no impact - triggers following errors: [ 50.627948] ucsi_acpi USBC000:00: unknown error 0 [ 50.627957] ucsi_acpi USBC000:00: UCSI_GET_PDOS failed (-5)
