Hi,
i recently upgraded a bunch of servers from 2.6.32.9 to 2.6.32.28 (grsecurity 2.2.1-2.6.32.28-201101120010)
and experienced a couple of "hard lockups".
I already posted this to lkml, but i appears that grsecurity is the reason (spin_lock spinning forever in d_real_path)?
See http://marc.info/?l=linux-kernel&m=129647198207816&w=2 for the short Thread on lkml.
Would be great if someone can have a look - I can provide additional details if neccessary.
Regards,
Sebastian
