Reassigning to David Howells.

Comment 2 David Howells 2011-03-14 12:23:36 UTC

Hi Daniel,

It looks like you've not included a couple of lines before the start of the trace that you've pasted that say what the kernel's complaint actually is.

Could you have another look in your logs?

David

Created attachment 50792 [details]
netconsole log

I only have the netconsole logs available. This shows some other cachefiles problems, too.

Comment 4 Florian Mickler 2011-03-29 21:17:07 UTC

Is this still a problem in 2.6.38.y?
