I can't tell from dmesg or syslog what is happening, but when I switch to TTY and execute a restart, I see some nouveau errors popup. I can login fine when I go back to 3.5 kernels.
Update: I managed to get logged in using the KDE Failsafe session. I'll have to see if I can figure anything out from the logs. I thought I might be able to login regularly after logging in via KDE Failsafe, but it still "freezes" after username/password authentication.

Sometimes, these changes make the standard new kernel not compatible with all of your existing hardware unless you make some tweaks and recompile by yourself. It is up to you to review what has changed and if it is worth the change for your config. Some other times your will only have to wait for bugfixing or for the next newer kernel
For example, kernels 3.3, 3.4 and 3.6 didn't work correctly (at least) on my main configs, although 3.2, 3.5, 3.7 and now 3.8 did wonders.
Edit: don't forget either that you will have to recompile and reinstall any out-of-tree drivers (like network or GPU proprietary drivers) in order to make them work with a new kernel version.

However the keywords of the kernel maintainer are "All users of the 3.8 kernel series must upgrade."
Until yesterday I kept 3.8.11 as a desktop fallback, since I already use 3.9.1 on my desktops.
eanfrid wrote:Yep except for one of my desktops I didn't really have to go to 3.9. The 3.8.x series is already a very good one.

PS: I have SSDs as (boot+system+apps) drives on all my PCs and I would not revert to HDDs for this part.
The is part of the role of a kernel maintainer, so yes.Does Ubuntu backport relevant 3.9 bug fixes to RR's 3.8.y?

I use 2x2TB HDDs in RAID1 for data on my desktop server and 4x1TB HDDs in RAID10 on my second server. So each of them has 2TB of real data storage and use 1 SSD for system and programs
As far as you avoid to write/rewrite a heavy load of data on a common consumer SSD (less than 10-15GB per day), its life expectancy is far superior to a HDD and is not a real concern.
Edit: I would never buy a used (?) SSD/HDD on Ebay or elsewhere. You can't test the hardware health before you buy and have no warranty.
