static grub_err_t
grub_raid_read (grub_disk_t disk, grub_disk_addr_t sector,
grub_size_t size, char *buf)
case 0:
case 1:
case 10:
{
read_sector = grub_divmod64 (sector, array->chunk_size, &b);
Bean, this is a bit wrong because array->chunk_size is 0 in the RAID 1
case and sector is 0 too in the case I got with gdb.
The easiest fix would be probable to just set chunk_size to for example
64.
Attached patch does it, but maybe you have a better/other idea?
