A320M-ITX BIOS Update Creates PCIe Problems

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I updated the BIOS to try and fix some occasional instability (freezes), and my PCIe card isn't working anymore. I get continuous I/O Errors with the drives on the card.

The drives are healthy and the card had been working for years before the update. The only thing that changed is the BIOS version.

Motherboard: ASRock A320M-ITX
BIOS: 7.40
CPU: AMD Ryzen 2400G
PCIe: PCIE x1 to 4 port SATA Card // Part No. P-PCE4SAT-A01-003
OS: Debian 'Bullseye' Linux (5.10.140-1)

Errors:

Any tips to get the card up and running again?

	Hi Perhaps the latest BIOS versions disable CSM by default, have you checked? You can confirm it in BIOS checking Boot tab. Good luck

	CSM is still enabled. I toggled it both on & off to no avail.

	[SOLVED]: I bought a Gigabyte motherboard and the problem is gone.
