I have experienced a number of minor problems with 2.6.26.5 & RT patch. The network interface giving random timeouts, intermittant hard disk failures, and assorted spinlock reports via dmesg. Downgrading to 2.6.26.2 with the latest RT patch, and the problems disappear. Might be worth while reverting to an earlier 2.6.26.x kernel and see if your problems also vanish.
