 It looks like the kernel is doing something weird. Prehaps triggered
 by ardour or possibly a HD on the verge of breaking.

 Try booting your old kernel and see if that doesn't solve the problem
 or try updating to rt10, incase there's a bug in rt7.
 Note that the rt-patches are somewhat experimental and might not
 be entirely stable at all times.
