Turn off the internal and external caches during the install.
This will work.
If you used a non-compressed kernel, that would work too.
You can't get a non-compressed kernel because it would blow things
out to yet-another-disk, and This Would Be Bad.
Several people claim that this is not a caching/compression
interaction. Yet it works. Therefore the hardware is apparently
cleverer than they are, and these several people are plainly wrong.
While they continue to rightously claim "This Should Not Fix It",
you can post responses agreeing or disagreeing from the system
you were able to install by assuming they were wrong.
You can turn the caches back on after you install because the
interaction is very specific to the kernel decompression code,
which is the same in the bootblocks (and in the compressed exec
loader -- don't try to run compressed executables, it's an
undocumented feature anyway) and you should have no more problems.
