B650E Taichi Lite WD SN850X Boot & Sleep Issue

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


   - With BIOS versions 2.02 and 2.00, experienced the following issues on an ASRock motherboard:
   - Cold Boot: System boots into UEFI BIOS screen, displaying an A6 error on the Dr. Debug screen.
   - On Save & Restart: Successfully boots into Windows.
   - On Sleep: Sleeps and the when resume from sleep, shows windows login screen briefly then a Blue Screen of Death (BSOD), with no dump file created.

Specs:
- B650E Taichi Lite
- WD_BLACK 4TB SN850X NVMe
- 64GB DDR5-6000 G.SKILL
- ASUS TUF RTX 3090 OC

Troubleshooting Steps Undertaken:
- BIOS and System Adjustments:
   - Disabled Fast Boot in BIOS.
   - Enabled CSM (Compatibility Support Module).
   - Reset BIOS to default settings, which also disabled AMD EXPO.
- Hardware and Firmware Updates:
   - Updated SN850X firmware to the latest version.

Resolution:
- Downgraded BIOS to version 1.30.AS02 [Beta].
- This downgrade resolved both the A6 error on cold boot and the BSOD issue after sleep.

- Is there a known compatibility issue with the newer BIOS versions (2.02, 2.00) that could be causing these problems?
- Any insight or updates regarding this would be appreciated, as it seems the issue is specific to the newer BIOS versions.

	I confirm I have no such error with initial 1.26 BIOS. The only problem I have is that when booting on system with EFI partition on one disk and the system (be it windows or Linux) on another partition, sometimes I get stuck to first stage boot prompt because the disk with the system has not been found. If having EFI parition and system on same disk I did not encounter that up to know. And system to am is working on Linux. I would love to get a 2.X BIOS but I'm not sure it is that stable ATM.
