Understandable.
We've been unable to pin down what triggers this bug, so we are unable
to reproduce it synthetically. It only appears to happen on shared
servers with lots of NFS traffic, and in all cases it happened with more
than a month of uptime. Also, we are unable to put an upstream kernel on
a production machine.
These two conditions will make it exceedingly unlikely that we would be
able to work this out with an upstream kernel.
Even if we were able to reproduce this with an upstream kernel, if it
takes such a long time to reproduce could that have aged the kernel
we're testing enough to invalidate our testing results?
Cheers!
Iordan
