I found this softlockup bug involving arts daemon using a
linux-2.6.14-rt6 kernel (with "Complete Preemption" and "Detect Soft
Lockups" compiled in).
This bug does not happen everytime: I was able to reproduce it only
three times in a week. Here is the oops message (obtained from my
printer because system is frozen):
