I have only recompiled the kernel several times, but never had a stability problem. There were some rumors on the unoffical AMD web site that there may have been an early batch of the K6s which had a bug which delayed the initial shipments. If you guys got ones from the early batch not long after it first came out, this could be the cause of the problem. What motherboards are you guys using? If any of the FreeBSD users got their K6s from authorized resellers, the cpus may be under a full 1 year warranty despite the fact that the resellers claim 1 month only. Overclocking of course voids it (AMD also warns that using any voltage above the specified voltage can damage the cpu). Things to notice... Not sure if this is accurate, but it appears that new K6s do not show the "PR2" but just the clock speed. Do they have a B on the top surface?
