Hm, that's weird, I've never seen that. I always thought that this is taken care
of by patchadd - when it noticed that a patch wasn't installed completely, it
backs out all changes it made. When patchadd isn't atomic, things will become
unpredictable.
I'm not sure how the CPU patchset determines if a kernel patch was
successfully applied, but the patchset script will notice the incomplete
kernel patch installation and try to reapply it.
I couldn't find anything in the patchset install script on a quick glance (it's
a loooong script). But I really think that it should be patchadd which should
take care of that, not some other script.
Without knowing the exact conditions of such a partly-failed patch install, it
will be impossible to add a workaround to PCA, I'm afraid. If you have more
details, feel free to post them here and/or report it to Oracle.

Thanks much, David Cashion
