Esta placa-mãe com uma configuração de inicialização tripla, inicializando no modo AHCI
Aqui está a mensagem relevante (extraída de dmesg ), observe o longo atraso no registro de data e hora entre eles:

Parece funcionar bem no Windows. É apenas uma questão do Ubuntu.
Todas as minhas unidades parecem estar firmemente conectadas, sem jumpers, a maioria é SSD, mas algumas são IDE. Eu tenho como 6 unidades. Um é um Hackintosh (drive GPT Mac) e outro é o Windows. Um SSD está conectado via eSATA
Eu não sei se ata2 é o mesmo que /dev/sdb , mas se for, isso pode ser interessante:
$ sudo fsck /dev/sdb
fsck from util-linux 2.31.1
e2fsck 1.44.1 (24-Mar-2018)
ext2fs_open2: Bad magic number in super-block
fsck.ext2: Superblock invalid, trying backup blocks...
fsck.ext2: Bad magic number in super-block while trying to open /dev/sdb
The superblock could not be read or does not describe a valid ext2/ext3/ext4
filesystem. If the device is valid and it really contains an ext2/ext3/ext4
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
e2fsck -b 8193 <device>
or
e2fsck -b 32768 <device>
Found a gpt partition table in /dev/sdb
Um comentário sobre a causa: link
Porque é uma unidade hackintosh da GPT:
$ sudo gdisk /dev/sdb -l
GPT fdisk (gdisk) version 1.0.3
Partition table scan:
MBR: protective
BSD: not present
APM: not present
GPT: present
Found valid GPT with protective MBR; using GPT.
