vorlon said the instability appears after a few days, with buildd running and eating 100% of the CPU.
If the instability affects a 300 Mhz UII module (typically in an U10 or an U5), then it might very well be faulty hardware. A lot of modules fitting that description suffered serious cache problems ; the symptoms were transient uncorrectable failure in the L2 cache, resulting in a kernel panic. At my old labs, we had 6 of those delivered in one bunch, and we had to replace at least 5 or 6 modules (at least one machine had the module replaced twice). -- Romain Dolbeau <romain@dolbeau.org>
