Wrong and wrong. First of all it's quite amateurish for me that the
email i did export for 'IOMMU patch' was not the right one, so i did
get few horrible deaths while the I/O load was involved more heavily.

Now i can't anymore kill it with the same load i did kill it in minutes
before, so the esp part seems still solid with the new driver.

The sad part is that when i finally did got the right IOMMU-patch in
and booted, the qlogicpti-driver did break as below. I know i could
hack in a if() for 'SBUS_DMA_NONE', but i'd rather not as i have no
idea how the SCSI-layer generally works ....

qlogicpti happily initializes when i just turned the plugged D1000 off
