Activating swap... failed.



Greetings,

Sometime during boot, i get the message "Activating swap... failed."
('failed' is in red)
The only place in /var/log (that i thought would make sense to search
in) i can find a reference to swap is:

$ cat /var/log/kern.log.0 |grep swap
Mar 21 12:28:37 deb64 kernel: [   12.194854] Adding 1951856k swap on
/dev/sda5.  Priority:-1 extents:1 across:1951856k

Swap is defined:

$ cat /etc/fstab

But not active indeed:

I barely ever use more than 1GB of RAM, but i guess linux uses swap
for other purposes. Or can i deactivate it entirely?

I've read i could mkswap but... it worked for ages, why get borked
now?! I've been having issues with the system time (it's one hour off
into the future and i haven't had time to work on your suggestions),
could that be realted? Unfortunately most results i found were in
italian...

TIA,
Nuno Magalhães
