| |
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. > > 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
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.
