I've found that I can consistently crash (oops) the module by SIG-INTing the splat userland process during the atomicity test. I presume it has to do with writing to a defunct fd (ioctl response) or with destructing the testcase state early (_fini function called early?)
This looks, however, different from the above case, which is why I attach the other (SIGINT triggered) kernel trace as well - it is quite lengthy because it appears to dump for all running threads

Hi sehe,
How were DEBUG_KMEM and DEBUG_KMEM_TRACKING set in spl_config.h when you hit the NULL pointer derefernce?

This memory allocation issue should be fixed by commit 1012968. Basically the issue was there were several cases when vmem_alloc() could fail which the Solaris semantics don't allow for. The behavior has been changes to retry the allocation until it succeeds although this might re-manifest itself as a hang and linux watchdog. Unfortunately, there's not much that can be done about that in the short term.
The second SIGINT issue was fixed by commit 8f813bb and was simply a bug in the test case.
