Adding myself here:
while enumerating USB after connecting a dongle, I also get
ucsi_acpi USBC000:00: unknown error 256
unknown error 0 seems to be random.
Gentoo, kernel 6.14.7
I haven’t noticed any consequences to this error so far. (I’ve had my framework 13 for 5 hours so far)
We are aware of this issue and are working on reproducing this and trying to fix it.
I would suggest if you are running into this. try the following temporary workarounds:
do a full system shutdown.
This should be:
Shutdown.
Unplug all power sources.
Wait 90 seconds.
Power back on.
The second workaround is to blacklist the UCSI_ACPI module temporarily.
Add blacklist ucsi_acpi
To
/etc/modprobe.d/blacklist
