You appear to be right, sir. The SVGA xserver was what I was using. Changing over to use the S3 server, and then adding back in MTRRs, seems to have solved the trouble. I'll let you know if it returns, but for now, all appears well. Victor -- Victor J. Orlikowski == [EMAIL PR

After doing some googling It would appear that, in Family 5, Model 8, Stepping 12 of the K6-2, AMD used a different CPU core, that was more similar to the K6-3, and that there is a slightly odd way of doing write-combining. Perhaps this is the problem? Anyone with more knowledge on the AMD co

This is precisely my problem. K6-2, model 8, stepping 12. Thus far, everything is *fine*, as long as MTRR is not compiled into the kernel. If MTRR is compiled into the kernel, I get lock-ups in X *only*, and the entire machine locks. I have no data on other CPUs; as I said, I previously had a P166

Hello all, Recently, I upgraded my poor Socket7 system from a P166 to a AMD K6-2 running at 400 MHz. The only change I made to my kernel config with the upgrade was to add in MTRR support. My kernel is a stock 2.2.18pre25, with the addition of the S3 framebuffe
