RAM: 2GiB DDR registered RAM. - Software Kernel: Any vanilla 2.4+XFS or 2.6 kernel. OS: Debian GNU/Linux. - How to reproduce: Access floppy drive using mtools or mouting for 2-5 times and the system locks up hard, with nothing responding. On a Computer with CPU activity LED's, those LED's stopped flickering, which means that no single bit continued working after the problem occurs. - Comments: I was unable to get any OOPS or backtrace since such info could not even be written to the disk or screen. I first though of a hardware specific issue, but since the new Athlon MP's are behaving the same, it seems to be more widespread. I would try to fix it myself, but i'm too busy fixing my own bugs on other drivers :P Best Regards Manuel.
