The issue is that a call to

(I'm saying probably, because gdb seems to be buggy on my machine and I
don't really trust its output, so I rely on strace instead, but that
doesn't support backtraces on the PA-RISC.)
I have the attached io_uring patch on 6.1.46. It's back ported from 6.4.
libuv make check was successful on my system.
Did the libuv check failed on 6.1.46 for you?
I just tried plain 6.1.49 and my machine crashed....
