Does any one install Centos 7 on Thinkpad t470p

[newcent]

Hardware:
Thinkpad t470p
intel 7700HQ
samsung 16GB memory
hard disk:
7200 HDD(500G) + Kingston SSD(256GB NGFF2242)
when boot from USB，then select the entry "Install CentOS ", it will show warning " Unkown Intel PCH(0xa153) detected " "warning:Intel Kabylake processor with unknown PCH--- this hardware has not undergone upstream testing. Please consult http://wiki.centos.org/FAQ"
"nouveau 0000:02:00.0: unknown chipset (1180d0a2)"
"ata4.00: revalidation failed (errno=-5)"
after serveral minutes, Installer quit with "/dev/root not exist", and the result of command "ls /dev" won't show the SSD I plus myself, it only show 500G HDD and U-disk which I made installer.
and if I change the boot string from "hd: lable XXX" to "hd:/dev/sdb4", Installer can startup, and enter the graphic installer, but I can not see 256GB NGFF2242 SSD. So I guest centos does not support skylaker with SSD now. any one can help?

Did you use CentOS 7.3 ?

Did you check the sha256sum of your downloaded iso file against the list published in the CentOS Release Notes? How did you create your USB stick to perform the install - there are many that are broken and try to be clever and rewrite the iso file as they write it to the USB stick and they invariably break it. Check http://wiki.centos.org/HowTos/InstallFromUSBkey for a list of the known-to-be-broken utilities and avoid those - use dd if possible,

TKS , no problem to install centos, but it can not recognize my additional SSD(NGFF2242). After yum update, the kernel update to 3.10.0-514.21.1.el7.x86_64, the warning disappeared and it can recognize SSD some times(Not always, I thought there still some bug in the kernel). And I can't use the trackpoint, maybe driver not supported. Anyway, I can use centos on it.So, I am waiting for centos7.4, maybe centos7.4 will support thinkpad t470p perfectly.

I think you will need to use a newer kernel than the one provided with CentOS-7. That would make your CentOS-7 install "not-supported", but it's just a laptop so I would go for it.

Here you have some tutorial: https://www.ostechnix.com/install-linux ... os-ubuntu/
(Not tested by myself, caveat emptor.)

There should be no problem accessing any sort of SSD, nvme or ahci or otherwise.

It's not the kind of disk, but the kind of chipset in the motherboard. The OP said he's using a Kabylake CPU from Intel, and those come with a new fangled chipset, and that chipset needs proper kernel support.

The best course of action, in this case, is to upgrade the kernel version, IMHO.

For which Redhat backported support...

Well, it seems such backporting of hardware support is not all-inclusive... I don't see mention of "0xa153" devices here:

Kernel 4.10 is needed to properly support Kabylake, in all of its variants and permutations.

It looks some bug in kernel, some time OS can recognize SSD and thinkpad's trackpoint, some time it can't.Here is the different dmes log in different circumstances.
