Hi All
We met a issue with SLES12SP1 on Intel Greenlow platform.
After install OS with "entire hard disk to make auto partitions" on SSD, system may hang up with a high rate.
When system hang, screen show:
i8042: No controller found
Couldn't get size: 0x800000000000000e
MODSIGN: Couldn't get UEFI db list
Couldn't get size:0x800000000000000e
