Hi all, on my custom 85xx board I can't do a soft reset. I'm using u-boot 1.3rc3 that has the latest cpu/mpc85xx/cpu.c patch to fix some type of reset problem. When I press the software reset button on my board after my nfs kernel panic, I get this:
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(2,0) Rebooting in 10 seconds..Machine check in kernel mode.
