[Bug 973486] [NEW] error: invalid blocklist

[Otus]

Public bug reported:

>From bug #972221 comment #4:

I get this message at boot after the most recent grub update. I didn't
get it before and didn't see any errors when updating grub. (It did ask
and overwrite my /etc/default/grub which I had modified.)

--

Unlike the reporter of that bug, I still see this with version
1.99-21ubuntu1 of the grub packages. It doesn't come up every boot, but
every once in a while (may be connected to whether I reboot to/from
Windows or do a hard boot, but can't say for sure).

The exact error message is:

"error: invalid blocklist

Press any key to continue..."

This message comes up after the Ubuntu kernel has been selected.
Pressing a key lets the boot continue normally.

Additionally before the grub screen comes up a black screen with the
message "error: invalid blocklist" repeated twice flashes by quickly.
