AMD FP7-20G 8845HS Freeze/reboot

Hello,

I bought the CWWK AMD 8845HS Octa-core NAS motherboard Dual 10G Ethernet ports 8 drive bays Dual ASM1164 expansion SATA3.0 / PCIE X16 (AMD FP7-20G ) and i have some trouble of reboot/freeze :

Ports list  :

• * USB 3.2 Gen 2
• * Type C
• * DP 2.1
• * HDMI 2.1
• * 2 x USB 3.2 Gen 1
• * 2 RJ45 10G
• * Jack 3.5

The other hardware i have is

• * CORSAIR SF750  (750W)
• * CORSAIR VENGEANCE SODIMM DDR5 RAM 16Go  4800MHz CL40  (CMSX16GX5M1A4800C40)
• * SSD 500Go nvme Crucial P3 plus CT500P3PSSD8
• * 4 HDD WDC WD80EFPX-68C4ZN0 8TO
• * 2 HDD ST2000VN004-2E4164 2TO

Software :

• * Kernel : Linux 6.12.57+deb12-amd64
• * Debian 12 Bookworm
• * OpenMediaVault 7.7.24-7

Since the beginning the mother board freeze/reboot without a lot of informations inside the log (Brutal reboot/freeze).

At start, with the default parameter inside the bios, the motherboard was freezing / restarting during a simple APT install in debian.

I have updated the bios with the official bios version from CWWK.

Generally speaking the motherboard freeze without explanation sometimes but also with specific operations :

• * During a backup and the use of Rsync
• * Media Service who scan the HDD (Plex, Jellyfin, Radarr or Sonarr).

The freeze is not linked to a specific SFF-8643 cable and occur on both

I have done some test :

• * MemTest --> Ok
• * Stress CPU --> Ok
• * Stress CPU + Stress IO --> not Ok
• * Smart HDD + Nvme --> Ok
• * HDD always on
• * HDD with sleep mode

I have also try some parameters inside the bios (All parameters set is in the bottom of the post) :

• * Eco mode : H Series OPNs System Config 4 (35W)
• * PCIe Loopback mode : Disabled
• * ASPM Mode and Hotplug Mode disabled
• * Change Slot Bandwidth : X4X4

Some bios settings help and reduce the number of freeze like the slot bandwidth

I have also set some parameters in debian :

• * processor.max_cstate=1
• * nomodeset
• * pcie_aspm=off

Some parameters helps me to reduce the amount of freeze to 1/2 freeze by day but the bug didn't disappear.

I hope i have put enought details, don't hesitate to ask for more.

Thanks for the support
