We're deploying a new version of Athena based on Ubuntu,
and we have a clever logout cleanup. Unfortunately when that
clever mechanism fails, it reboots the system. So we're getting
a lot more reboots than is normal. AFS hangs in an oops here.
We have been running for a couple weeks the patch:
/afs/andrew/usr/cg2v/cbr-only-free-what-you-alloc.diff
Apparently that patch does not remedy the problem for the original
reporter, but it DEFINITELY DOES remedy the problem we're having that
looks like the same thing.
I am opening this RT so that we can explicitly track the issue, and
fully understand what the root cause is, what the most appropriate patch
is, and to make sure that that patch becomes part of OpenAFS in the most
efficient manner possible.
I've been unable to ocr the images I took of the kernel oops trace,
but I did use gimp to coalesce the images in the Ubuntu bug into one,
easy to read image. I've attached that image to this case.
How can I help move this issue forward?
