Don't know what kind of information is 'preferred', but here goes for
nothing .... no toying with "init=/bin/sh". Those are for ....

Took the IOMMU + new ESP patches and ..

Hardware is 8-way E3500 w/ 7GB (ATM) memory installed. There are two
36GB disk behing ESP and two behind Qlogic (= my backup plan :)
There is also CD-ROM and DDS-3 plugged to ESP-bus and at least the
DDS-3 is working fine (didn't even test the CD-ROM still).

Past about two hours the machine has pushed the OS part of disks once
to DDS-3 with tar and no problem. Now it's doing same with dump while
compiling RPMS - no problems what so ever.

The ESP part of the kernel messages comes up as following.

Something else? Long term stability and some _real_ I/O load is still
something to be tested ......
