The OS indicated last time that there were updates available so I installed them. I am not sure if that is the cause of the problem.
Yup - sounds like it.
1. Boot back into Suse Linux
<= There are two methods:
a) You can select an older kernel from the grub menu, like gumaheru suggested
... or ...
b) You can boot into "rescue mode" from your original install CD/DVD
2. Go into "yast", and perform *another* kernel update
Select "yes" to any defaults
3. Upon reboot, the problem should very likely be resolved
Please post back how it goes, in any case.
Thank you in advance ... and good luck!
