It's a 53c8xx: we load the "firmware" into it from our own driver.
I just had a look at esiop.ss, and it looks high-level enough that it's
plausible to me that the problem is with whatever's backing that code,
whether silicon or ROMed firmware or whatever.
I just verified that I see the same on a 53c875 using esiop(4), and it
also does the same thing with siop(4). I also found that it works fine if
the buffer is at an even address and only failed on odd addresses. It's
been quite a while since I was working on the Amiga driver with similar
chips, and I don't remember if there was anything special needed with odd
addresses. Next time I've got my Amiga on, I'll try the test program
there. I've also got a 53c875 in an Alpha that I plan on testing.
