I had the opposite problem on a Zenith 386SX, which, when optimized with QEMM, would freeze. It turns out that the Zenith has a "slush ROM" that it writes to high RAM, and the area it writes to should not be used for anything else. Try excluding E000-E7FF from use in high RAM. That might solve the problem.
