With 2.5.59-mm10, dbench runs normally. I ran this: ps -ewo user,pid,priority,%cpu,stat,command,wchan with the 2.5.60 System.map copied to /boot, and got this: root 1103 15 0.1 S /usr/sbin/sshd schedule_timeout steven 1104 15 0.0 S -bash wait4 steven 1142 15 0.0 S ./dbench 1 wait4 steven 1143 16 0.0 S ./dbench 1 pause steven 1153 16 0.0 S /bin/sh /home/st wait4 steven 1154 16 0.0 R ps -ewo user,pid - I control-c'ed the dbench 1, and started ./dbench 4, and got this: root 1103 15 0.0 S /usr/sbin/sshd schedule_timeout steven 1104 15 0.0 S -bash wait4 steven 1143 16 0.0 S ./dbench 1 pause steven 1160 15 0.0 S ./dbench 4 wait4 steven 1161 16 0.0 S ./dbench 4 pause steven 1162 16 0.0 S ./dbench 4 pause steven 1163 16 0.0 S ./dbench 4 pause steven 1164 16 0.0 S ./dbench 4 pause steven 1166 16 0.0 S /bin/sh /home/st wait4 steven 1167 17 0.0 R ps -ewo user,pid - That process 1143 is now unkillable with kill -9. After control-c-ing the ./dbench 4, I now have 4 dbench 4 processes which are unkillable with kill -9. The system is 2-way PIII, kernel is SMP, PREEMPT.
