"Badblocks" is running since yesterday on one of both harrdisks (and is still
running...for more then 10 hours now (1TB to check)) and I 
got thise errors visible via dmesg:

(I dont know, where the report sequence starts, so I put some
repetitions here in) 

They do not grow in count and badblocks did not report anything
onto the console where I start it.

I started it with

    solfire:/root>badblocks -v -n /dev/sda

At midnight, the DSL connection had been cut by the provider
and automagically reestablished by my linux box, but I dont
think, that this has something do to with it.
Additionall smartd is running in the background...

Smartd's smartd.conf contains this (first try...;)

/dev/sda -a -d sat -o on
/dev/sdb -a -d sat -o on

What the heck is going on in my system?

Thanks a lot in advance for any help !

Best regards,
worried,
mcc
