Clarifications about AMD TLB L3 bug

by Robert Myers <rbmyersusa@[EMAIL PROTECTED] > Dec 13, 2007 at 04:35 PM

A number of assertions have been made here about the AMD TLB L3 Bug:

1. Only affects virtualization.

2. Is fixed in 64-bit Linux without a significant performance hit.

1. TRUTH: AMD, which knew about the bug before the chip was released,
falsely made this claim.  The bug apparently affects all workloads,
potentially resulting in a system freeze.

2. TRUTH: A fix is available under NDA for RHEL 4 and not otherwise
apparently.
