So, for a workaround I disabled extattr support in libarchive. > Can you verify that this helps you, too? I today noticed the same problem on -CURRENT i386 built March 9. Immediately before my last buildworld (running sources from a couple months ago probably) I didn't have any lockups and portupgrade was working fine. Now portupgrade-invoked tar put the system into something like livelock--tar unresponsive at %100 cpu, kill -9 ineffective, sometimes other processes unresponsive, reboot hangs before completing and a reset or power-cycle is required. I am using ZFS and initially thought that was the source of the regression but I haven't produced the lockup with anything but tar and the extattr removal hack seems to have fixed it fow now (though I'm sure there's a better fix out there..). Thanks and let me know if I can provide additional details or testing. JN
