Problem manifest itself exactly the same as this dpm problem.
The original description of this report says: "screen becomes blank after grub trying to boot it". Please file your own report.
I don't know what else I can do to help with this.
Please run a kernel built from commit 77497f2735ad6e29c55475e15e9790dbfa2c2ef8 (the commit before 02376d8282b88f07d0716da6155094c8760b1a13) for at least a few days to make sure it doesn't happen with that.
