Description Nicolas Mailhot 2006-07-15 18:29:23 EDT
Linux 2.6.17-1.2401.fc6 #1 SMP Sat Jul 15 04:12:46 EDT 2006 x86_64 x86_64 x86_64

On boot:

[ INFO: possible circular locking dependency detected ]
cpuspeed/1556 is trying to acquire lock:
 (&policy->lock){--..}, at: [<ffffffff8026899d>] mutex_lock+0x2a/0x2e

but task is already holding lock:
 (cpucontrol){--..}, at: [<ffffffff8026899d>] mutex_lock+0x2a/0x2e

which lock already depends on the new lock.
