 RAM filesystem

Hi,
I've got some troble when I tried to use init ram fs on riscv64 virt.
The default ext2 fs works fine. If I use cpio and init ram fs to
replace that. The kernel can boot up with small ram fs, but
a big ram fs(>100M) doesn't work.
kernel got into panic and report "junk within compressed archive"
static long __init flush_buffer(void *bufv, unsigned long len)
{
        char *buf = (char *) bufv;
        long written;
        long origLen = len;
        if (message)
                return -1;
        while ((written = write_buffer(buf, len)) < len && !message) {
                char c = buf[written];
                if (c == '0') {
                        buf += written;
                        len -= written;
                        state = Start;
                } else if (c == 0) {
                        buf += written;
                        len -= written;
                        state = Reset;
                } else
                        error("junk within compressed archive");
This check failed.
Someone knows how to solve this problem?

Thanks,
Mao Han
