5.14.0-1023.25 seems to work fine. I used the steps similar to https://lore.kernel.org/io-uring/CABVffEM79CZ+4SW0+yP0+NioMX=shhoobcefbhqs6g6hex2...@mail.gmail.com/
cmake -DPLUGIN_{MROONGA,ROCKSDB,CONNECT,SPIDER,SPHINX,S3,COLUMNSTORE}=NO -DWITH_URING=ON ../mariadb-server make -j8 mysql-test/mtr --mysqld=--innodb_use_native_aio=1 --nowarnings --parallel=4 --force encryption.innochecksum{,,,,,} --mysqld=--innodb_io_capacity=50000 --mysqld=--innodb_io_capacity_max=90000 And it failed twice with 5.14.0-1022.24, while it finished twice on 5.14.0-1023.25 ** Tags removed: verification-needed-focal ** Tags added: verification-done-focal -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1952222 Title: io_uring regression - lost write request To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1952222/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
