[CentOS] Kernel panic since CentOS 5.2 upgrade

Hello,

since upgrading to CentOS 5.2 my notebook hangs while booting with
a "Kernel panic - not syncing: Fatal exception" error. Here is a
screenshot: http://www.istari.de/olaf/centos/r0013878.jpg

Ok, that toshiba tecra 8000 notebook is very old, but I use it as a thin
client. And for that it makes a great job.
I have had no such problem under CentOS 5 and 5.1.

Should I stay with kernel 2.6.18-53.1.21.el5 or is there a workaround?


Thank you very much.
Olaf
