Hi!

I have tested further.

The following smartctl options work although the harddisk is busy:
-H
-i
-c
-A
-l error

But those crash the computer (but only if the harddisk is busy):
-l selftest
-l selective
-l xerror

I have found another interesting thing. In a harddisk idle state I get
this error for -l xerror:
(The [ number ] lines come from kernel printk)

In this case works the soft resetting.

Ideas are welcome.
Thank you!
