https://bugzilla.kernel.org/show_bug.cgi?id=43359 --- Comment #5 from Anonymous Emailer <anonymous@xxxxxxxxxxxxxxxxxxxx> 2012-06-14 16:16:35 --- Reply-To: muthu.lkml@xxxxxxxxx I am using CentOS 6.x and I hit this bug with 3.5-rc2. I tried to look in to the boot process and found that the initramfs generated from 3.5.-rc2 is not good for lvm root. It was missing /lib/modules/<uname -r>/kernel/drivers/md/*". Also /sbin/ doesn't have lvm_scan and was missing a bunch of other files too. CCing initramfs folks. Any help?
