So I have this VM (I don't have access to the host system) running Debian Lenny, with the following kernel: 2.6.32-bpo.5-686 #1 SMP
This morning I upgraded the VM to Squeeze (finally), and as the system rebooted, I noticed that it was painfully slow. The dist-upgrade (after reboot) is still running, and has been for several hours. However, the load is below 1, CPU usage around 50%, no big disk activity, and there is plenty of RAM available. I don't understand where this performance problem (it's really, REALLY slow) come from. The odd thing though, is that the clock seems to be very slow as well: the seems to believe that only a few minutes have passed since it has been rebooted, even though it's actually been hours.
Has anyone experienced a similar problem? Or do you have suggestions about where to look for clues?
