When the soft lockup occurs.  I can move the mouse but it doesn't click. 
Keyboard repeats the last key pressed a couple times (2-20, depending on the
hang duration).  Music stops, I get silence but mp3/ogg rolls on

Version-Release number of selected component (if applicable):
This is my grub.conf line.  If y don't use the extra parameters it hangs when
booting X

kernel /boot/vmlinuz-2.6.21-1.3228.fc7 ro root=LABEL=/1 rhgb quiet noapi
c nolapic irqpoll

How reproducible:
Boot the machine and work

The nvidia driver is heavily involved in this backtrace. Suggest the bug be
reported to nVidia:

Thank you for the report.  For users who are experiencing problems
installing, configuring, or using the unsupported 3rd party
proprietary "nvidia" video driver, Nvidia provides indirect
customer support via an online web based support forum.  Nvidia
monitors these web forums for commonly reported problems and
passes them on to Nvidia engineers for investigation.  Once
they've isolated a particular problem, it is often fixed in
a future video driver update.

The NVNews Nvidia Linux driver forum is located at:


Once you have reported this issue in the Nvidia web forums,
others who may have experienced the particular problem may
be able to assist.  If there is a real bug occuring, Nvidia
will be able to determine this, and will likely resolve the
issue in a future driver update for the operating system
releases that they officially support.

While Red Hat does not support the proprietary nvidia driver,
users requiring technical support may also find the various
X.Org, XFree86, and Red Hat mailing lists helpful in finding

X.Org mailing lists:
