Affected as well. I installed Ubuntu 13.04 64-bit yesterday night on my self-assembled desktop PC and have seen the issue a few times since. I would say in 80% of all attempts, Ubuntu 13.04 boots fine for me.
It seems like it usually happens the first time after I turn on my PC, but not when I reboot from within Ubuntu. When I reboot from my Windows partition, the issue occurs as well.
I will keep an eye on it and report on any other patterns I see.
I am running Ubuntu with the proprietary NVidia graphics drivers and heard they could be involved in the issue, so I will look for a way to safely remove them completely and revert to Nouveau.
I will also attach the outputs of lspci, lscpu and lshw later tonight.
