I will try creating a swap partition on my second drive to see if that improves things ... I am able to cause a panic "on demand" but a crash dump is rarely written (presumably because the system believes the device is not accessible?). I must have crashed it 10-20 times now with various corruptions of the panic screen - once it had blue text with "trap 12 trap 12" all over the screen, I liked that one ;-). I did manage to complete a "make index" while the background FSCK was running, once it had finished, performing the same task caused a panic locking the machine up again with no crash dump. John
