Description Alexandre Oliva 2006-07-22 16:35:11 UTC 
Re-enabling the second cpu, after disabling it, causes an oops on cpufreq.

Right now I can't get to the picture of the oops I took, but I'll do so ASAP
(probably no earlier than tomorrow, unfortunately)

Version-Release number of selected component (if applicable):
kernel-2.6.17-1.243[12].fc6
(it worked on 2405.fc6)

How reproducible:
Every time

Steps to Reproduce:
1.Boot up an SMP system
2.Log in
3.echo 0 > /sys/devices/system/cpu/cpu1/online
4.echo 1 > /sys/devices/system/cpu/cpu1/online
  
Actual results:
Oops

Expected results:
No oops
