This is the IMA problem that's popped up here in the past, and is being tracked by RT #125704 These aren't ooopses or panics - they're simply calls to dump_stack(). The main problem with them is that they can significantly slow down your machine - you'll get one output for every file in your cache directory upon startup, and you'll probably also see them in normal operation. Sadly, this is a problem with the Linux kernel that we can't fix - the IMA interface in 2.6.31 and 2.6.32 is broken, and unusable by out of tree filesystems. The interface has been completely redesigned in 2.6.33. You can fix this if you're prepared to rebuild your kernel, and disable the CONFIG_IMA option. Hope that helps, Simon. _______________________________________________ OpenAFS-info mailing list [email protected] https://lists.openafs.org/mailman/listinfo/openafs-info
