Swap is a partition on the 1st disk.

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.
