Hi,
I'm new to SCSI and all it's subsystems and this is the first time I'm
having troubles with it. This morning I got the folowing kernel error
message:

And I have no idea what could this mean. For me it's just a list of
interesting sounding words like BDR, SCB etc. Could you please tell me
what should I be expecting from this system soon? It's a high priority
system, runing hundreds of apache daemons showing hundreds of banners
every second.

Thank you very much for your comments on this. By the way, any idea
where could I get documents on clippings like SCB, ACCUM, QINFIFO
etc.?
