I was hoping someone might have some ideas on what might have happened
with the following oops/BUG(). This is on an embedded PPC running
2.6.16-rc5. From the description I got from my coworker who say this, he
was doing NFS on the system and at the time the oops occured his desktop
linux box X froze up as well. So some odd network activity.
I just looking for some direction at things to look at or a better
understanding of what might have gone wrong.
Thanks
