Comment 6 for bug 1763611

The attached dmesg shows an almost exactly 30-second gap in output from the kernel, with no messages after the gap implying kernel driver timeouts, it just immediately mounts the root filesystem. Not much evidence to suggest that this is an SSD issue. Also, if it's reproducible in a 64-bit virtualbox environment, it's not an SSD issue. I'd suggest starting by looking for timeouts in any lubuntu-specific casper logic.
