> my system will lock up hard,  and the cpu activity lights will show only one CPU active.   I am running the redhat 6.0 kernel (2.2.5-15smp).     Is there some bug in the driver that lets this scratched up CDROM lock the system?

The AHA1542 has some known problems with bus reset handling. 2.2.14 has some
fixes for this but Im not sure if they are all everyone will need

> I have tried to upgrade my kernel to 2.2.14 which works fine, BUT the new kernel does not bring up my RAID-5 array of disks,  I always have to go back to the stock redhat kernel.  Anyone have any Idea what is up there?

Red Hat (like most vendors) ships the enhanced raid patches (raid-0.90) so you
need to build a kernel with that added.
