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.
