Subject: fb1 /var full after reboot, caused all sorts of problems 

Jonathan Hanks pointed me to this fix to the gpstime kernel module that was unfortunately put in after the 3.4 release that we're currently using:

https://git.ligo.org/cds/advligorts/-/commit/6f6d6e2eb1d3355d0cbfe9fe31ea3b59af1e7348

I hacked the source in place (/usr/src/gpstime-3.4/drv/gpstime/gpstime.c) to get the fix, and then rebuilt the kernel module with dkms :

sudo dkms uninstall gpstime/3.4
sudo dkms install gpstime/3.4

I then stopped daqd_dc, unloaded gpstime, reloaded it, restarted daqd_dc.  The messages are no longer showing up in /var/log/messages, so I think we're ok for the moment.

NOTE: the fix will be undone if we for some reason reinstall the advligorts-gpstime-dkms package.  There shouldn't be a need to do that, but we should be aware.  I'm discussing with Jonathan if we want to try to push out a new debian package to fix this issue...
