    It does :)

    I suspect there is a problem writing to the consoles...

    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?

    PS Back in a couple of hours...
