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?

Thank you and best regards,

Kenneth Parker, Seattle, WA
