9-STABLE: Chelsio t4nex0: failed to pre-process config file: 2.

[John]

Hi Folks,

   I have a pair of Chelsio T4 cards installed in a new HP DL380
system. The driver does not load at boot time, failing with the
message:

t4nex0: failed to pre-process config file: 2.

   After the system has finished booting, if I then issue a 
'kldload if_cxgbe' command, the driver loads correctly. Note,
the driver loads correctly from the command prompt with or
without the if_cxgbe_load in /boot/loader.conf.

   The message is coming from t4_main.c:partition_resources().
I don't see anything obvious that would cause this:

        rc = cfg ? upload_config_file(sc, cfg, &mtype, &maddr) : ENOENT;
        if (rc != 0) {
                mtype = FW_MEMTYPE_CF_FLASH;
                maddr = t4_flash_cfg_addr(sc);
        }
        
        bzero(&caps, sizeof(caps));
        caps.op_to_write = htobe32(V_FW_CMD_OP(FW_CAPS_CONFIG_CMD) |
            F_FW_CMD_REQUEST | F_FW_CMD_READ);
        caps.cfvalid_to_len16 = htobe32(F_FW_CAPS_CONFIG_CMD_CFVALID |
            V_FW_CAPS_CONFIG_CMD_MEMTYPE_CF(mtype) |
            V_FW_CAPS_CONFIG_CMD_MEMADDR64K_CF(maddr >> 16) | FW_LEN16(caps));
        rc = -t4_wr_mbox(sc, sc->mbox, &caps, sizeof(caps), &caps);
        if (rc != 0) {
                device_printf(sc->dev,
                    "failed to pre-process config file: %d.\n", rc);
                return (rc);
        }

   Has anyone run into this?

Thanks,
John
