The Ubuntu-5.04 kernels have the libata EH bug, whereby the entire machine locks up at random once in a blue-moon when EH is running. On the machines here, this bug is most often triggered by simply having an empty CD/DVD reader that is managed by libata -- polling for disc insertion triggers the EH code every couple of seconds, leading to random lockups. Bug no longer present in newer kernels, but the Ubuntu-5.04 stock kernels still have it. Cheers
