It's all pretty obvious. The first is checking page size vs. cache size and whether it's VI or does anything unusual; thus far things look hopeful that flush_dcache_page() analogues are unnecessary. More information about Super-H is needed to wrap up what will probably be no more than an audit. The second is a triplefault on x86-64 under some condition involving a long-running database regression test. There has obviously been considerably less progress there in no small part due to the amount of time required to reproduce the issue.
