But we have not isolated which change is actually causing it.Do you use any initrd ? If so how do you pass its address to the kernel ?
What is your kernel load address ?
can you send your .config file you're using ?
I'll send it to you later, since I'm not at the office right now.
We do know that reverting back to the 2.6.19.x arch/mips/kernel /setup.c will fix the issue. We will continue to dwindle it down until we come up with the offender.What did the console say ? If nothing early console may help if available.
All I get is this inflate: decompressing elf64: 00080000 - 0037701f (ffffffff.80326000) (ffffffff.80000000) elf64: ffffffff.80080000 (80080000) 2957446t + 151450t net: interface down
