I am quite lost by you developers on this bug.
First, no one seems to have comment on the fact that original poster have
nothing to do (as far as I see) related to kernel bug.
In fact, I see no usefull errors information in Jarno files except maybe:
Oct 10 16:01:24 ubuntu grub-installer: The file /boot/grub/stage1 not read
correctly.
Oct 10 16:01:24 ubuntu grub-installer: error: Running 'grub-install
--no-floppy (hd0)' failed.
at the end of syslog.
Then, I can only guess you have confirmed Marc Tardif bug about zlib oops that
have followed the zlib error:
