Hi!

In my QEMU Debian GNU/Hurd instance, I do some stuff (GDB testsuite, for
example), and then issue a =C2=BBsudo shutdown -r now=C2=AB.  This doesn't
complete, but hangs like this:

      PID  UID  PPID  PGrp  Sess TH  Vmem   RSS %CPU     User   System Args
    [...]
    28386    0     1 28386 28386  2  147M 1.67M  0.0  0:00.00  0:00.01 /bin=
/sh /etc/init.d/rc 6
    28391    0 28386 28386 28386  2  146M 1000K  0.0  0:00.01  0:00.00 /lib=
/startpar/startpar -p 4 -t 20 -T 3 -M stop -P 2 -R 6
    28413    0 28391 28386 28386  2  147M 1.72M  0.0  0:00.00  0:00.00 /bin=
/sh /etc/init.d/sendsigs stop
    28418    0 28413 28386 28386  2  146M  668K  0.0  0:00.00  0:00.00 sync
    [...]

The sync is hanging; confirmed with a manually run =C2=BBsyncfs -s=C2=AB wh=
ich also
hangs.  What seems suspicious is the following:

      814    0     5     1     1 15  141M  984K 99.8  0:00.23 11:47.19 /hur=
d/console

..., and indeed if I =C2=BBkill -KILL=C2=AB that one, some time later (?), =
the
shutdown proceeds.


Gr=C3=BC=C3=9Fe,
 Thomas
