Vague reports like this are sadly a regular occurrence, and they usually happen when people don't update their initrd after updating their kernel. As well as the obvious problems from incompatible modules, some versions of distros are worse than others, as they foolishly hard-code device numbers, and a new kernel happens to assign device numbers in a different sequence breaking everything. Another cause is when the distro lets the boot script run too early without waiting for the kernel to discover all the devices necessary. Or sometimes kernel/module changes mean it no longer sees the devices at all.
