I recompiled (rc4+patch) with sysrq support, suspended, resumed and tried sysrq-t but got no output. I *can* change VTs and see the various login prompts, bitmap messages and the console messages. Caps/Num lock lights work. Fearing incompetence I tried sysrq-s sysrq-u sysrq-b and got a reboot so sysrq is OK. Any suggestions on how to see more? Or what to try next? Any other kernel debug options to set?
