It looks like ABI breakage to me -- the reason why mpd worked for me (qemu fails the same way) is most likely due to: * on x86_64 I'm using mpd in user session which in default configuration does not use io_uring (mpd requires 64M `ulimit -l` while by default 64K is available) * on ARM I'm using system instance but mpd was compiled with liburing 0.7 After quick look at liburing commits between 0.6 and 0.7 I'd say it would be this one: https://github.com/axboe/liburing/commit/0f0517331307605e576b3492c93dc4988e06fdc0 _______________________________________________ pld-devel-en mailing list [email protected] http://lists.pld-linux.org/mailman/listinfo/pld-devel-en
