I did some more debugging of this. First of all, I tracked
down the problem to the fs/nfs/t_rquotad test script.
Instead of running the full test suite, the problem can be triggered
manually by running:
This will yield a bunch of output including
tc-so:Executing command [ rump_server -lrumpvfs -lrumpnet -lrumpnet_net
-lrumpnet_netinet -lrumpnet_shmif -lrumpfs_nfs unix://clientsock ]
tc-so:Executing command [ rump.ifconfig shmif0 create ]
tc-so:Executing command [ rump.ifconfig shmif0 linkstr shmbus ]
tc-so:Executing command [ rump.ifconfig shmif0 inet 10.1.1.100 ]
tc-so:Executing command [ mkdir /rump/mnt ]
(at this point, there is a one-minute pause)
tc-end: 1381146179.891394, get_nfs_be_1_user, failed, Test case timed out
after 60 seconds
Although this output may look like the "mkdir" command is timing out,
the timeout actually happens in the following command,
mount_nfs 10.1.1.1:/export /rump/mnt
which ATF fails to log (that's PR 48285).
If I add a "sleep 1" between the "mkdir /rump/mnt" line and the
"mount_nfs" line, the test passes.
I still don't know what causes this, but perhaps the above contains
enough clues for someone to figure it out.
