I've been testing for about half an hour or so (probably a bit more) now. Still using DEBUG_VFS_LOCKS, and I've tried the test case several times, ran an initial backup (i.e. destroy target pool and send|recv the entire pool) and a few incrementals. Rebooted, tried it again. No panic, no problems! :) Let's hope it stays this way. So, in short: With that patch (copied here just in case: http://exscape.org/temp/zfs_vnops.working.patch ) and the libzfs patch linked previously, it appears zfs send/recv works plain fine. I have yet to try it with clone/promote and stuff, but since that gave the same panic that this solved, I'm hoping there will be no problems with that anymore. Regards, Thomas
