error: mounting /dev/root on /sysroot as ext3: No such file or directory

[Xu Nao]

I have compiled a new kernel(linux-3.0.0) this afternoon. But when I reboot my system, I got an error:

Unable to access resume device (UUID=3cbed94b-dd95-42f4-933f-b8d68bf538d9)
mount:error mounting /dev/root on /sysroot as ext3: No such file or directory

I've tried many method found on this forum,But it doesn't work.

result of blkid:

[xunao@localhost ~]$ blkid
/dev/sda8: TYPE="swap" LABEL="SWAP-sda8" UUID="3cbed94b-dd95-42f4-933f-b8d68bf538d9"
/dev/sda7: LABEL="/" UUID="610a231f-5668-4f9b-be4c-a97ded78e639" TYPE="ext3" SEC_TYPE="ext2"

I found the UUID of swap partition is the same that appeared in the error.
I have rebuilt the initrd-3.0.0.img with mkinitrd:

mkinitrd -f initrd-3.0.0.img 3.0.0

But the problem all the same!

Current OS is Fedora 10 (2.6.27.5-117.fc10.i686)
Any help will be appreciated!
