The message does not show on a similarly configured HP/DL-380g4 (CCISS instead of AACRAID) running rc3. Anything to worry? Anything I can do to help debugging?
This is enabled by CONFIG_DEBUG_STACK_USAGE, which defines check_stack_usage. It is called on task exit and will warn each time a task has used the biggest kernel mode stack since booting. This isn't a bug, and isn't a (bad) warning, it's just informational right now.
