Description Tim Kientzle freebsd_committer freebsd_triage 2009-03-11 17:20:06 UTC 
See bin/132452 for the initial reports of this.

I added extended attribute support to tar recently and
several people reported that making an extattr_list_link
syscall on a ZFS volume hangs the CPU (100% system time)
and results in an unkillable process.  This has been
reported on both amd64 and i386 architectures with recent
-CURRENT.

I don't have a machine with ZFS handy to try to reproduce
this myself; I don't know if this affects 7-STABLE; I don't
know if it also occurs for extattr_list_file or other extattr
system calls.  I'm eager to get this fixed so I can turn
tar's extended attribute support back on.

How-To-Repeat: touch foo
lsextattr -h user foo
