I have AMD Athlon XP1600+ with 623 MB of ram.
It was running fine with kernel 2.6.32-31-generic until I installed the latest updates. After updating Ubuntu requested to restart the computer. As soon as the computer boots, the system crashes immediately, starting up, crashing, also.
When a key is pressed, the Grub menu appears. After selecting the kernel 2.6.32-31-generic the system boots normally.
Both 2.6.32-32 entries (normal and recovery) are crashing. There are no visible entries in the log-files made. What can go wrong? How can I figure out what is going wrong?
