Hello,
I am seeing some scary looking kernel bug entries in my dmesg under
2.6.1-mm5. Its behavior varies.... I first rebooted my machine under
2.6.1-mm5 remotely, and when I got home I found the computer frozen at the
bug screen.
However, I rebooted it, and I saw the bug in dmesg again, but the system
fully booted and was useable this time.
Now, I rebooted for a second time, and the bug shows up twice (!) in my
dmesg. It definately only showed up once under the last reboot. Even so,
the boot completed and my computer is useable (I'm typing this e-mail
under 2.6.1-mm5).
Since its the scariest looking, below is the 2 kernel bug reports from my
current boot. Under that I included my complete dmesg from the previous
boot, then I included alot more configuration information under that.
Please note I did not load the nvidia kernel module until AFTER boot time
(after I encountered these bugs).
thanks,
Jim Faulkner

hmm. There was a patch in that area which I have subsequently dropped
because it was really fixing devfs problems in the wrong place.
Perhaps Andrey can ask you to test a subsequent patch if he takes another
look at this.

please try this one. This basically does the same inside of devfs. It passed
usual sanity checks here; I cannot reproduce oops you have (do you have SMP
system?)
I appreciate if someone with more intimate knowledge of fs/namei.c comments if
conditions in devfs_d_revalidate_wait make sense.

Yes, I have an SMP system.
Your patch works! I applied it to 2.6.2-rc1-mm1 (which is the last -mm
version that doesn't kernel panic on me because of an unrelated bug), and
the "kernel BUG" warning has gone away.
