Hi Michael,

This seems to be a different issue. Not related to thread-imc. Similar perf fuzzer issues are reported in
https://bugzilla.linux.ibm.com/show_bug.cgi?id=161854
https://bugzilla.linux.ibm.com/show_bug.cgi?id=162507

See this comment: https://bugzilla.linux.ibm.com/show_bug.cgi?id=162507#c37

One workaround can be: try with these patches as well:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=3202e35ec1c8fc19cea24253ff83edf702a60a02

Above patches fixes two issues. But there are still cases where lockup can still happen.

Thanks,
Anju
