Hello,
Testing 2.6.29-rc2-git1, I notice something which doesn't happen with
2.6.28.1 on the same machine with the same config (minus new config
entries for 2.6.29) : when the machine is idle, the load average
reported by top is not 0.00 (it is with 2.6.28.1) but between 0.30 and
0.80 and either ksoftirqd/0 or ksoftirqd/1 is listed as number one in
top output, with a few % of CPU. The machine seems to work fine but
I think something is still wrong.
Here is an example of top output :
top - 17:23:40 up 19 min, 2 users, load average: 0.42, 0.48, 0.34
Tasks: 99 total, 1 running, 98 sleeping, 0 stopped, 0 zombie
Cpu(s): 0.2%us, 0.5%sy, 0.0%ni, 99.1%id, 0.0%wa, 0.0%hi, 0.2%si, 0.0%st
Mem: 2075420k total, 311920k used, 1763500k free, 4912k buffers
Swap: 1212896k total, 0k used, 1212896k free, 115648k cached
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
4 root 15 -5 0 0 0 S 1 0.0 0:30.74 ksoftirqd/0
1 root 20 0 2100 692 588 S 0 0.0 0:00.47 init
I attach dmesg, config and /proc/interrupts. Feel free to ask more info
if needed.
Best,

The problem is still present in 2.6.29-rc2-git3 on this P4 machine, but
I do not see it on a Centrino laptop.
Config has not changed and I do not know if /proc/interrupts is useful
or not so I am not attaching anything for now, feel free to ask for more
information and I will do my best to provide it. I know someone else
also experienced this problem on his machines.

Sorry for this half-true claim, after double check, the problem is
*also* present on the Centrino laptop.
