Fwd: Linux 6.5.5 - kernel BUG with ucsi_acpi

[Bagas Sanjaya]

Hi,

I notice a regression report on Bugzilla [1]. Quoting from it:

> 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.

See Bugzilla for the full thread.

Anyway, I'm adding this regression to regzbot:

#regzbot introduced: v6.4..v6.5 https://bugzilla.kernel.org/show_bug.cgi?id=217960
#regzbot title: ucsi_acpi boot crash when USB drive is connected to USB-C port

Thanks.
