Ubuntu Server 13.10 appears to be very unstable, I got random crashes of the system with no apparent reason and nothing is showing in syslog.
This is screenshot from the console when the crash occurred
Anyway I think it's actually caused by the new kernel 3.11. I would like to downgrade to 3.4 to check it. Is it possible?
sudo aptitude search linux-image indicates that only versions available I've is 3.11 kernel:

UPDATE
tried to install the kernel from
http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.4-precise/
but ubuntu hangs at " Loading Initial Ramdisk"
UPDATE 2
looks like my system crashes are related to this bug: bugs.debian.org/cgi-bin/bugreport.cgi?bug=734172
apparently fixed in 3.12.6, but again ubuntu hangs at " Loading Initial Ramdisk"
Best Answer
You probably need to downgrade your version of Ubuntu, as those kernels are what's available in 13.10. Try this guide.
Otherwise, you could try grabbing an older kernel version from a stable LTS version: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.4-precise/
