Hello Oleg,

No external modules were loaded when I triggered the lockup I mentioned 
in the patch description. Although the SRP test software I referred to 
earlier can be run against the SCST SRP target driver, I'm using the 
in-tree LIO SRP target driver to reproduce this lockup. BTW, I think it 
is unlikely that the target driver framework is involved in the lockup 
since I have observed this lockup before when no SRP target driver was 
loaded on the test system. The same lockup also has already been 
observed with md-raid.

Thanks,

Bart.
