(BTW, I have found the AMD folks to be very responsive, although I wish there was a solution to the known chip bug.) I will continue to chellenge AMD to find a means to test the "errata" chips for the HALT bug, but so far I have received consistant information from multiple AMD sources (per the attached). AMD is very interexted in supporting Linux and I have offered to work with them to test the K-7 on 2.0.x and 2.1.x SMP (They are already testing Linux on UP K-7). I expect that testing to begin in 1Q99. Cheers, Lyle -- Lyle P. Bickley | Bickley Consulting West Inc. [EMAIL PROTECTED] | 1697 Grant Road V 650-428-0621 | Mountain View, CA 94040 F 650-428-0599 |
In essence all model 6 and model 7 processors are affected by this erratum. Only a subset of the model 8 processors are affected (AMD-K6-2). However, there is no way, through software or visual inspection, to determine if you have a stepping of the model 8 that resolves the erratum. All shipments of the model 9 (AMD-K6-3), which will be launched next year, will not be affected.
