I have been running Linux 3.13-0.bpo.1-amd64 for a few days, without problems. I let aptitude upgrade me to Linux 3.14-0.bpo.1.-amd64, and now the machine hangs during boot. (This is on bare hardware Toshiba laptop).
I see these lines on the screen: > early console in decompress_kernel > Decompressing Linux... Parsing ELF... done > Booting the kernel. and then it hangs. There is nothing written to any logfiles from this aborted boot. Luckily grub lets me boot into 3.13-0.bpo1-amd64, which still seems to work OK. Please let me know if I can provide any other information ?
