Bug Description
Currently, after updates done to edgy on 10/9/06, syslogd and klogd are eating up all CPU cycles. The system is extremely sluggish. Once these processes are killed, everything runs fine. Dmesg reports a ton of errors with the i915 graphics adapter, which are mostly variations of:
[17181284.716000] validate_cmd( 54f00006(2) ): 8
[17181284.716000] i915_emit_cmds(365)
[17181284.716000] i915_emit_cmds(369)
+1 here.
My CPU is working overtime and here are the culprits. The top command revealed the following:
[PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
3810 root 16 0 1728 516 420 S 21.8 0.0 4:02.02 dd
3784 root 16 0 1652 620 500 R 18.5 0.0 3:13.49 syslogd
3812 klog 15 0 2428 1312 384 S 3.3 0.1 0:44.97 klogd
As you can see the CPU is being gobbled my those 3 programs that started running after I got the latest kernel updates and restarted.
EDIT: When I did a ps -ef on PID 3810 this is what came up:
ps -ef | grep 3810
