1) Does the BIOS have "Windows MBA mode" Enabled. This also can cause login to not occur. You can find this option in the CTRL+K option on the Broadcom Nic option ROM during post. 2) Do you see any segfault messages in the /var/log/messages for brcm_iscsiuio ? 3) Using ps command can you determine if the brcm_iscsuio daemon is still running ? 4) If you could post your /var/log/messages and /var/log/brcm-iscsi.log to some paste-bin, equivalent that would be great.
