Hello, But,this is not the answer on this problem( kernel stuck when decompress initrd) I also worry about the same proglem. I'm trying to run LINUX 2.2.13 image on our custom board. I also found the kernel stopped in flush_window() in drivers/block/rd.c after showing following messages on console.
Does anybody advise on this problem?
