>Description:
It seems to me that the system has to be up for a day or so
for this to take effect, but the symtom is that reboot or halt will
not reboot or halt. Several times, I have tried taking it to single
user mode, and then unmounting the disks. Unmounting my news spool
hung the system there.
Now when I come back up out of either one of these problems, I
find that there are never any problems --- so the sync is working
(doesn't complain at all abou the disks in fsck), but the actual
unmount (setting the clean bit?) never happens.
Note that if the machine is up a few hours it will normally
reboot. I'm wondering if this may be something that expire does to
the disk, but I have no hard data. I think that I have dump
technology finally mastered if a kernel dump might help you (how do I
trigger one is a good question).
