Content-Type: text/plain; charset=us-ascii; format=flowed Content-Transfer-Encoding: 7bit Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org Hi, I have a Debian based system with a custom 2.4.7 kernel compiled with gcc version 2.95.4 20010703 (Debian prerelease) (also saw the same with 2.2.10+ gcc 2.95) The CPU in the machine is a AMD K6 200MHz, and has 64MB of SDRAM I reomved the heatsink and the serial is Cxxxxxxxx, however in the kernel boot messages I get the following, Aug 17 09:06:49 phoenix kernel: CPU: Before vendor init, caps: 008001bf 008005bf 00000000, vendor = 2 Aug 17 09:06:49 phoenix kernel: AMD K6 stepping B detected - <6>K6 BUG 9016725 20000000 (Report these if test report is incorrect) Aug 17 09:06:49 phoenix kernel: AMD K6 stepping B detected - probably OK (after B9730xxxx).

I have 64MB (the amount that triggers the bug IIRC) in the system and the the kernel and everything else compiles without generating a SIG11. Is this a false detection or would it be possible that I have a wrongly tagged CPU? Also the link http://www.mygale.com/~poulot/k6bug.html does not exist.
