We recently did fresh installs of CentOS 4.4. That's when the problem started happening. The system works perfectly fine otherwise, it's just a problem with the reboot process. Since these are servers in a data center, it's vital that they be able to reboot without intervention. Did something significant change with CentOS 4.4 that could be causing the problem? Thanks.
