It works most of the time, but sometimes it fails with a kernel crash stack. The last message before the crash is always: "Trying to unpack rootfs image as initramfs...." Below is a sample stack from the crash. Does any one have any clues on tracking down this issue? Cheers, Ivan BUG: soft lockup - CPU#0 stuck for 67s!
