I got this, right after apt-get upgrade (plus direct installs of kernel). The message shows up on bootup. My system has not locked up yet, which is why I prefer this to bug 1215513. In my case, the Logical Block is 314223. I did (under root): fdisk /dev/ram0, followed by "p". This shows up, as if it's a hard disk: 255 heads, 63 sectors/track, 13 cylinders, total 314224 sectors. Note that total sectors is one higher than the logical block the error message is complaining about. Is it as simple as to find the script under the ramdisk part of bootup that sets up zram0, and decreasing the number of sectors?
