Verrry eeeenteresting (showing my age): Kdiff3 if fantastic. Looked at the entire source tree for -rt1 and -rt7. Found nothing changed touching any of the "oopses" that I have seen. What has been added, however, seems to be the trace-back code to display them. (Hypervisor code has been removed but my PIII clunker has no kvm support in any event.) Am I correct? These displayed "oopses" are problematic or simply debugging messages? They seem to not have effected anything outside of my log files :-) Safe to ignore them and keep using -rt7 or wait on this?
