All of these partitions had space_cache,inode_cache enabled. Linux 3.14 has broken resume on my desktop, hence I need to shutdown and restart the machine every time. But even on clean reboot, inode_cache was constantly being rebuilt on each boot. It caused kdm/X to timeout, even getty weren't spawned. I had to reboot it with ctrl-alt-delete, just to make it usable again. 2 out of 3 times, I had to reboot more than once, to make it usable. While the disk was constantly grinding in the boot process, I ssh'ed into it from another machine and observed the inode cache overhead. Hence I disabled both the caches on all the partition(yes, I know, space_cache will stick around), and the machine is lot more snappier and responsive than ever before. I am running archlinux with 3.14.1 kernel. Thanks, -- Regards Shridhar
