Bart,

I am working to try to reproduce the KASAN warning. Unfortunately, so far I am not able to see it
in Ubuntu + Linus' kernel (as you described) on metal. The config file is different but copies
the CONFIG_KASAN_xxx exactly as yours. With KASAN enabled it hangs on every iteration of srp/002
but without a KASAN warning. I am now building an openSuSE VM for qemu and will see if that
causes the warning.

Thanks for the support,

Bob
