I am seeing such messages quite regulary when starting a connection over
CDMA USB modem, kernel 2.6.17-1.2405 on i686. And also I am getting

Jul 22 09:19:08 certp kernel: 
Jul 22 09:19:08 certp kernel:
=========================================================
Jul 22 09:19:08 certp kernel: [ INFO: possible irq lock inversion
dependency detected ]
Jul 22 09:19:08 certp kernel:
---------------------------------------------------------
Jul 22 09:19:08 certp kernel: ksoftirqd/0/3 just changed the state of
lock:
Jul 22 09:19:08 certp kernel:  (&ap->xmit_lock){-+..}, at: [<f9277226>]
ppp_async_push+0x2f/0x3ae [ppp_async]
Jul 22 09:19:08 certp kernel: but this lock took another,
soft-irq-unsafe lock in the past:
Jul 22 09:19:08 certp kernel:  (&port->lock){--..}


Is there a Bugzilla entry where I could contribute?
