Description Acu Ilie Dorin 2018-09-27 13:46:36 UTC
FreeBsd 12.00 cannot be installed on 4 different AMD Ryzen Laptops (Manufactured by HP, Dell and Huawei)
The system halts immediately following the FreeBSD initial Welcome to FreeBSD screen.

I will describe in detail the HP ENVY 360 Ryzen 7 messages (following by more brief descriptions of Dell and Huawei Laptops)

HP ENVY x360 Convertible 15m-cp0xxx (15.6 inch screen) - from BestBuy
Product Number: 4AC55UA#ABA
Born on Date  08/12/2018

The installation USB Stick is with 

During first boot with usb stick, following the Welcome to FreeBSD I can see two things
Warning: WITNESS option enabled, expect reduced Performance
SVM (disable in BIOS)
ACPI APIC Table: <HPQOEM 8497 >
Firmware Warning (ACPI): Optional FADT field Pn2ControlBlock has valid Length but zero Address: 0x00000000000000000000/0x1 (20100010/tbfadt-796)

acpi0: PowerButton (fixed)
acpi0: wakeup code va 0xfffffe00033ff00 pa 0x9d00
That is the last message where it hangs.

I tried the same usb stick on three different AMD Ryzen Laptops as Following:

ON HP Envy 360 13.3 inch with Ryzen 5 the system halted also before the install:
last lines:

hpt27xx: no controller detected


BIOS Versuib 1.2.0 
Dell Inspiron 7375
AMD Ryzen 5 2500 u

the last message is also about
acpi_ec0: <embeded controler .... port ....)

I know more details are perhaps needed. Since there is no way to capture the text, except a picture, I could send some if needed.
I am not certain I will keep any of the laptops, perhaps I can do more testing on HP ENVYx360 15.6 inch laptop.
However, I wonder if FreeBSD can be installed in any AMD Ryzen Laptop.
Is this a EFI/BIOS issue, a CPU issue or Freebsd?

Is this a regression from an earlier install, or is this a new install?
