scsi-experts needed: target aborted

Hello dev-list

I was never able to access my scanner (UMAX astra 1200S, scsi).

mesh reports: target 6 aborted, interrupt in idle phase ?

Some time ago, somebody posted a patch (see end of message) to enable
scsi-debugging, which miraculously makes the scanner get recognized by the
kernel and work (partly) with SANE...
I had to disabled the patch again, because my log file (and the console) got
filled up with tons of debug infos.

Now my question to scsi-cracks:
Why does the device only gets registered with debugging enabled (no other
changes to mesh), and , even more important for me: What changes to mesh.c
would let me use the device without overloading my system with debugging infos?

Any hints greatly appreciated


(System: kernel 2.2.15pre19 on a Performa 6400)

this is the patch that enables debugging and lets the kernel register the
device (which should NOT be related anyhow ???):
