[ale] Ext4 kernel bug

[Lightner, Jeff]

Or if you aren't trying to be bleeding edge which Fedora is then you might want to consider CentOS 6 as it is a binary compile of RHEL source and won't require you to upgrade so often.

as that system is on f13 (dead, gone, should be updated IMMEDIATELY) it doesn't have a serious, if at all, issue with this kernel bug. It's very kernel version specific.

Don't upgrade to f15 as it's also dead (F18 is nearing beta) soon.
Back up the personal stuff and do a fresh install of F17 (and cuss a bit it the interface changes) or do a fresh install of Centos 6.3 (and add the EPEL repo for newer desktop toys).

Every time you stop a school, you will have to build a jail. What you gain at one end you lose at the other. It's like feeding a dog on his own tail. It won't fatten the dog.
