Hi, I'm having issue with a MegaRaid 9341-8i card which is properly working on two motherboards (kernel-5.10.25 and kernel-5.11.10) but not on a third for which I want it to work. I originally received this card with a firmware from 2018 and I've updated it to the latest from Broadcom website (24.21.0-0148) but in both cases, I've the same issue on the third motherboard: [ 14.013135] megaraid_sas 0000:01:00.0: BAR:0x1 BAR's base_addr(phys):0x00000000fe800000 mapped virt_addr:0x(ptrval) [ 14.013142] megaraid_sas 0000:01:00.0: FW now in Ready state [ 14.013148] megaraid_sas 0000:01:00.0: 63 bit DMA mask and 32 bit consistent mask [ 14.013933] megaraid_sas 0000:01:00.0: firmware supports msix : (96) [ 14.014439] megaraid_sas 0000:01:00.0: requested/available msix 5/5 [ 14.014445] megaraid_sas 0000:01:00.0: current msix/online cpus : (5/4) [ 14.014447] megaraid_sas 0000:01:00.0: RDPQ mode : (disabled) [ 14.014453] megaraid_sas 0000:01:00.0: Current firmware supports maximum commands: 272 LDIO threshold: 237 [ 14.014631] megaraid_sas 0000:01:00.0: Configured max firmware commands: 271 [ 14.015377] megaraid_sas 0000:01:00.0: Performance mode :Latency [ 14.015380] megaraid_sas 0000:01:00.0: FW supports sync cache : Yes [ 14.015388] megaraid_sas 0000:01:00.0: megasas_disable_intr_fusion is called outbound_intr_mask:0x40000009 [ 14.037098] megaraid_sas 0000:01:00.0: Init cmd return status FAILED for SCSI host 2 [ 14.037762] megaraid_sas 0000:01:00.0: Failed from megasas_init_fw 6399 Trying to rmmod then modprobe leads to something that looks like stuck state or such: [ 570.269770] megaraid_sas 0000:01:00.0: BAR:0x1 BAR's base_addr(phys):0x00000000fe800000 mapped virt_addr:0x00000000f42ba0e1 [ 570.269775] megaraid_sas 0000:01:00.0: Waiting for FW to come to ready state [ 570.269780] megaraid_sas 0000:01:00.0: FW in FAULT state, Fault code:0x10000 subcode:0x0 func:megasas_transition_to_ready [ 570.269782] megaraid_sas 0000:01:00.0: System Register set: (***) [ 570.269908] megaraid_sas 0000:01:00.0: Failed to transition controller to ready from megasas_init_fw! [ 570.269919] megaraid_sas 0000:01:00.0: Failed from megasas_init_fw 639 The motherboard which is not working is a recent one: Asrock X570D4U-2L2T with a Ryzen 3900XT. I've read a lot of things on internet saying that might be CSM issues or such but no luck with that. On the two working motherboards, it works in legacy/UEFI only. I've also tested the card on a x16 or x8 slots, the same result. I've attempted to build megaraid driver provided from Broadcom (07.716.01.00-2). Up to a slight adjustment in a log call using older attribute "host_busy", I'm hitting an unrelated issue due to KBUILD_CFLAGS recursion in arch/x86/Makefile. After hours and hours of testing, I'm currently out of ideas. Does anyone has an idea or could help me into adding useful debug info in the driver or such? Thank very much in advance, Frédéric
