I need to look at the registers that are at or around 0xe000ef90. Using mw and xd, I see that nsh does not support pointers greater than 0x7fffffff. A quick look at the source shows that the pointers for those two commands are set with calls to strtol() rather than strtoul(). Changing the two pointer-setting instances to strtoul() fixes the problem, at least for my architecture/config.
