It did append both with 2.6.8 and 2.6.9 kernel. I had no such problem with the same kernels on the Dell Optiplex sx270. No swaping enabled on any of the machines, and no kernel error message report. The main difference between the two is that the sx270 use ATA and Intel gigabit lan, and the gx280 use SATA and tigon3 gigabit lan. At kernel configuration level, only disk and network drivers are different.
