Indeed.
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?

David
PS Back in a couple of hours...
