Hi!

quoted

How hard does the machine freeze?  Can you use sysrq?  
If so, please
dump sysrq-t.

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.

Increase console loglevel by killing klogd/sysrq-9?
