            Bug ID: 217960
           Summary: Linux 6.5.5 - kernel BUG with ucsi_acpi
           Product: Drivers
           Version: 2.5
          Hardware: Intel
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P3
         Component: USB
          Assignee: drivers_usb@kernel-bugs.kernel.org
          Reporter: alxchk@gmail.com
        Regression: No

After update to linux 6.5.5 I observed several crashes during bootup when USB
drive connected to USB-C hub. To find out what has been crashed I enabled EFI
pstore. Unfortunately there were no crashes after that. However, there are
kernel BUG traces in dmesg. After several experiments I found strong
correlation between ucsi_acpi driver and the crash.

I blacklisted:
blacklist typec_ucsi
blacklist ucsi_acpi
blacklist roles
blacklist typec

Two dmesgs are in attachment. 

The messages to search:
ucsi_acpi USBC000:00: possible UCSI driver bug 2
ucsi_acpi USBC000:00: error -EINVAL: PPM init failed
