I have similar problems. I want to switch to 9.1 (from 7.2) because I need support of EPCS128. I found out that (one of) the reason for malfunction is the sof2flash command. If I generate the flash-files with sof2flash from 7.2. then the Nios will boot correct. I can use the flash utility from 9.1 SP1 (nios2-flash-programmer).

My workaround is:

use Altera 7.2 (or other except 9.1.) for

sof2flash --epcs --input=project.sof --output=project.flash

elf2flash --epcs --after=project.flash --input=firmware.elf --output=firmware.flash

use Altera 9.1 for

nios2-flash-programmer --cable='USB-Blaster [USB-0]' --epcs --base=0x3200000 project.flash

nios2-flash-programmer --cable='USB-Blaster [USB-0]' --epcs --base=0x3200000 firmware.flash
