Tried the patch. I see both before and after messages for hda, but when hde is probed I see neither. Briefly looking at the IDE code, I see the max request size: printk comes before either of those lines, as as nothing else is printed after that line (see original bug report), I can only assume the problem is somewhere before the write_cache().
I applied the patch on top of your previous changes, as they seemed innocuous enough.
