Please always include the probe messages !

The "extraneous data discarded" message 
indicates SCSI bus problems ...


Is this a one time problem, or does this 
happen every time you start your system ?

Can you send a boot message log of the 
last version that did work ?

Well, quite a number of devices ...
How long is your SCSI bus cable, BTW ?

Did you add devices lately ?

Have you tried to boot a kernel built with:

  options "SCSI_NCR_MAX_SYNC=0"

just to be sure it's not a problem with
cables or termination ?


I'm currently working on the PCI and NCR 
code and will stay for a few more hours.
I really would like to get this resolved 
rather soon ...
