Cool. xhci-hub is in your backtrace, and the above patch was made for
something very similar (though, again, I don't see why you're getting a
_crash_, it should _warn_ and continue normally). And, actually, also
include this patch:
https://lore.kernel.org/lkml/20230614181307.gonna.256-kees@xxxxxxxxxx/
This is now in Linus's tree:
09b69dd4378b ("usb: ch9: Replace 1-element array with flexible array")
Please also still try with the first patch I mentioned, which is very similar:
https://lore.kernel.org/lkml/20230629190900.never.787-kees@xxxxxxxxxx/
Hi,
I have finally built w both patches (and recommended PSTORE settings were
default already).
This second patch fixes the booting problem, but alas there is still a problem -
all Wayland and X11.org GUI applications fail to start, with errors like this one:
