This is caused by log2(0), this if fixed as follows:
diff --git a/src/ap/acs.c b/src/ap/acs.c
index aa5498e..04b1e31 100644
--- a/src/ap/acs.c

static u64 log2_sane(u64 val)
{
- return log2(min(1073741824, val));
+ return return (!val) ? 0 : log2(min(1073741824, val));
}
I'll send a new version of the last patch with this fix, thanks for
reporting this.
