Also seeing this on Ubuntu 24.04 with kernel 7.0.0-38 and 7.0.0-42, Dell Pro Max 18 Plus MB18250 (Intel Core Ultra 9 285HX), BIOS 3.5.2. ucsi_acpi USBC000:00: error -ETIMEDOUT: PPM init failed at every boot, after which /sys/class/typec is empty and the USB-C dock display is lost. modprobe -r ucsi_acpi && modprobe ucsi_acpi recovers it. After the reload, UCSI_GET_PDOS failed (-5) appears a few times. Kernel 6.17.0-1033-oem on BIOS 3.3.2 did not show the failure on 10/21. I haven’t tested 7.0 on the old BIOS or 6.17 on the new one, so I can’t say whether the kernel or the BIOS change is the trigger.
