still in trouble with 2.6.23.1-rt5 :(
.config:
http://www.rncbc.org/datahub/config-2.6.23.1-rt5.0
serial console capture:
http://www.rncbc.org/datahub/console-2.6.23.1-rt5.0-1.log
one thing about SysRq-T: while in the middle of a freeze it just doesn't
dump anything, just the 'SysRq : Show State' line. you can see that
several times on the console output above.
only when it is somewhat recovering, as said, by making some last resort
measures like SysRq-E as in 'SysRq: terminate All Tasks' for instance,
then SysRq-T will dump something. my guess is that this later dump will
be moot :/
back to production with 2.6.22.1-rt9 ;)
