 Thanks for your advice to be disabled "options preemption". After building 
 new kernel, my PC9821V166 become stable. Including the option large file 
 moving cause system hung, but now it could be completed.
 Sorry to late inform this result.

State-Changed-Why:  
You need to update the ATA driver as the race that caused failure  
with PREEMPTION has been fixed since then.
