慢速Ubuntu [ata2: SRST failed (errno=-16)]和[ata2: reset failed，放弃]

具有三重引导设置的这个主板，在AHCI模式下启动
下面是相关消息(从dmesg中提取)，请注意它们之间时间戳的延迟时间很长：

[ 61.104142] ata2: reset failed, giving up在Windows上工作得很好。这只是Ubuntu的问题。
我所有的驱动器似乎牢固连接，没有跳线，大多数是SSD，但有些是IDE。我有6个驱动器。一个是Hackintosh (Mac驱动器)，另一个是Windows。一个SSD通过eSATA连接。
我不知道ata2是否与/dev/sdb相同，但如果是，这可能会很有趣：
$ 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
or
e2fsck -b 32768
Found a gpt partition table in /dev/sdb对原因的评论：https://www.redhat.com/archives/rhl-list/2006-October/msg03892.html
因为这是一个GPT黑客驱动器：
$ 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.
Disk /dev/sdb: 1953525168 sectors, 931.5 GiB
Model: ST31000524AS
Sector size (logical/physical): 512/512 bytes
Disk identifier (GUID): 384E6D96-A1EE-4D32-8FE5-14B63E4BF049
Partition table holds up to 128 entries
Main partition table begins at sector 2 and ends at sector 33
First usable sector is 34, last usable sector is 1953525134
Partitions will be aligned on 8-sector boundaries
Total free space is 262157 sectors (128.0 MiB)验证磁盘通行证：
$ sudo gdisk /dev/sdb
$ v
No problems found. 262157 free sectors (128.0 MiB) available in 2
segments, the largest of which is 262151 (128.0 MiB) in size.回答 1

步骤1-识别ATA2
据猜测，ATA2引用了/dev/sdb。确定答案的方法是使用：
$ ll /sys/block/
total 0
drwxr-xr-x 2 root root 0 Apr 10 16:46 ./
dr-xr-xr-x 13 root root 0 Apr 4 21:05 ../
lrwxrwxrwx 1 root root 0 Apr 10 16:46 loop0 -> ../devices/virtual/block/loop0/
lrwxrwxrwx 1 root root 0 Apr 10 16:46 loop1 -> ../devices/virtual/block/loop1/
lrwxrwxrwx 1 root root 0 Apr 10 16:46 loop2 -> ../devices/virtual/block/loop2/
lrwxrwxrwx 1 root root 0 Apr 10 16:46 loop3 -> ../devices/virtual/block/loop3/
lrwxrwxrwx 1 root root 0 Apr 10 16:46 loop4 -> ../devices/virtual/block/loop4/
lrwxrwxrwx 1 root root 0 Apr 10 16:46 loop5 -> ../devices/virtual/block/loop5/
lrwxrwxrwx 1 root root 0 Apr 10 16:46 loop6 -> ../devices/virtual/block/loop6/
lrwxrwxrwx 1 root root 0 Apr 10 16:46 loop7 -> ../devices/virtual/block/loop7/
lrwxrwxrwx 1 root root 0 Apr 10 16:46 nvme0n1 -> ../devices/pci0000:00/0000:00:1d.0/0000:3e:00.0/nvme/nvme0/nvme0n1/
lrwxrwxrwx 1 root root 0 Apr 10 16:46 sda -> ../devices/pci0000:00/0000:00:17.0/ata2/host1/target1:0:0/1:0:0:0/block/sda/
lrwxrwxrwx 1 root root 0 Apr 10 16:46 sr0 -> ../devices/pci0000:00/0000:00:14.0/usb1/1-1/1-1.3/1-1.3:1.0/host2/target2:0:0/2:0:0:0/block/sr0/通过loop1条目忽略loop7。
sda(硬盘驱动器)在ata2频道上nvme0n1( SSD)在0000:3e:00.0上(实际上硬连接到CPU @ 40 GB/s)。sr0在usb1上
因此，您的第一步是在ata2上发现哪些设备
步骤2-检查设备
ide设备可以通过主/从装置链接，如果在ata2上，您可能需要检查它们的设置，同时逐个删除它们，以确定哪些是有缺陷的。
同样错误的人在ata2上发现了他们的DVD/CD驱动器是罪魁祸首和缺陷：“耐2:链接响应慢，请耐心”。
另一个人发现有缺陷的SSD是问题所在：ata1 1:链接反应缓慢，请耐心(ready=0)
无论如何，也可以运行fsck或其他驱动测试实用程序。
