Hi kefu, I checkout the latest ceph version, your code has already been merged in. Build with -DWITH_SEASTAR=ON success, but when I run seastar unit test, always got the error, seems seastar reactor not running. Then I write a simple seastar app, still got the same error, the checked out seastar version is 21553df. But your old working branch, all seastar unit test work in my machine, so don't know what is different between master branch and your working branch. The error message is: /ceph/src/seastar/src/core/reactor.cc:542: seastar::reactor::reactor(unsigned int): Assertion `r >= 0' failed. /ceph/src/seastar/src/core/reactor.cc:542: seastar::reactor::reactor(unsigned int): Assertion `r >= 0' failed. /ceph/src/seastar/src/core/reactor.cc:542: seastar::reactor::reactor(unsigned int): Assertion `r >= 0' failed. Aborting on shard 65.
