Hello!
One week ago we upgraded about 300 servers from 2.6.20.20 to 2.6.24.2.
Now we get sometimes dozent of processes in state DN. The system is
completely idle - but the load is 20 or 90 or whatever. And it can only
be "repaired" by rebooting the system.
I'm NOT on the LIST so please CC me.
Thanks.

Did you test with *one* server before upgrading all 300? If not, please do
and try to upgrade in smaller steps, e.g. 2.6.20->2.6.21 and see when it
breaks. Add a few *DEBUG .config options, they may help narrowing
down the problem...

please post sysrq-t (echo t > /proc/sysrq-trigger) output.

We ever do...

OK not really - i've tested the new kernel on all models. And it works
fine... the DN state only comes sometimes - absolutely not reproducable.
So my tests went OK and then we've done the update. I've now seen 5
servers in 7 days having this problem.

Sorry what key is sysrq? Can i also do this via SSH Console?

Problem here is that it is not reproducable...

just do the echo above and it'll have the same effect as the key, and yes
you can do this via ssh just fine (I do that all the time)

dmesg ring buffer is too small to fit this in. Please repeat it once again
with bigger ringbuffer (dmesg -s if you have this chosen in your kernel) or
post /var/log/meassages output of all processes. I see only waiters in
readdir, not seeing who could block them.
Which filesystem did you run du on?
Hello!
I'm using XFS. dmesg -s32000 does not help - no more output. In messages
there is also no relevant output. Other than what I've posted here:
http://lkml.org/lkml/2008/2/21/76
Sorry but i cannot recompile the kernel on all machines again - another
downtime is not possible at the moment.

Some kind of borkage in readdir, probably either in xfs or vfs?
