Start up 10 cp commands on the same partition, run hdparm -t -T /dev/sda and it will lockup within 10 seconds. The machine is rock solid under heavy cpu, with no io traffic. It never has kernel panic'ked (as i would expect with temperature problems.) If you perform more than one write command to the same partition at the very same time, no matter what the type drive/device it is, it locks up.
Does anyone else successfully run linux and debian testing on alpha's with 2.6 kernels?
