-------------------------------------------------------------------------------------
I have a number of Ubuntu Precise Desktop machines which are turned on
during office hours on a LAN which rely on /etc/fstab entries to auto
mount cifs shares to a Debian Samba server on the LAN. Normally this
works fine. Some machines have static IPs, some use DHCP.
Occasionally though, at boot time, I get a black screen of death with
stack trace dumped like that shown below. Note that often this causes
the entire system to hang, but that today it's continued to boot and
everything seems to be working, except the samba shares. It is usually
fine after a reboot.
There is no reason to suggest there is any problem at the server end
(nothing in syslog) and the server is in use by a dozen other machines
on the LAN which are successfully connected.
Sample output (I expect ubuntu-bug attached this anyway):
