Let me rephrase that: 1) sr m is broken in my version, (Its silent) don't know why. Hmm ... sr anything is silent (but/and error-free). 2) there's other /proc structures that are human readable and are interesting to look at during crash, e.g. /proc/pci, some stuff in /proc/ppc64 > I have considered a generic facility like gdb, based off stabs or dwarf > but decided against it for now.
