I accepted all types of flaming on this - the answer in most important.
Below I attach the output of dmesg:
This HP Netserver E60 box was running 3.5-STABLE. A few days back I
decided to push it to 4.2-STABLE. Now some strange device (not quite
strange though) takes the kernel about 15 seconds to probe, just as it
leaves the for SCSI devices to settle..hmmm..I never saw this with
3.5-STABLE, so I was just wondering if maybe I missed some option when I
compiled my 4.x kernel...
I have indicated using ^^^^^ the device that scares my life....
Thanks in advance.
