Intel has put on ice shipments of two flavours of 550MHz Pentium III Xeon chips after discovering a bug that caused eight–way servers to freeze. The bug disrupts communication between the processor and Intel's Saber motherboard. It is appears to affect only Xeons with 512KB and 1MB cache -- the 2MB beast has escaped unscathed from the bug, which causes machines to hang on boot up and serving up instead the dreaded Blue Screen of Death. Intel hopes to resume shipments of de-bugged Xeons (or maybe debugged Saber motherboards) in a couple of weeks or so. In the meantime, server OEMs could always give Compaq a call -- the PC vendor's own motherboards appeared to be immune to the Xeon bug. ®
