[Bug 1050774] Re: grub-script-check assert failure: *** glibc detected *** /usr/bin/grub-script-check: double free or corruption (!prev): 0x08210b38 ***

Latest news:

- see attached required grub.d taball

- all the hdds tested without errors (fsck)
- still get "alloc magic is broken at ..." before seeing the grub menu

but strangely, compared to the error with grub-install reported into the
#12 post above, updating then upgrading the latest grub packages was
done without trouble. Note also than gparted confirme than none of the
partitions are ext2, but as expected ext3/ext4 (curious).

As one of the pata hdd is only used for backup, and have some ntfs partitions only (plugged as primary master), i've tested to boot without that hdd (removed from the pc), and surprise, the pc boot normally: no more alloc magic broken . What is strange is these issues only have started on Sept 14, meaning the latest package upgrades have set a regression (now we need to find which one(s).
So now i have the other pata set as 1st master and the sata as 3d master and cdrom as 1st slave.
