There's a new errata kernel (2.6.18-164) from RedHat which appears to come only with RHEL5/update 4. Presumably that will be available whenever SL5.4 is released, is that correct? And what then is the schedule to back-port it to the earlier SL5's? Steve Timm ------------------------------------------------------------------ Steven C.
