I just got our RockyLake system running and recognized by the MCPC, but I'm having some other issues now. First of all, "sccBmc -i" sometimes displays errors during the MEMRD test after configuring the memory controllers the first time (please see attached file sccBmc.i.err.jpg). After configuring them again, no further errors are displayed, and the program exists normally; however, I wonder whether this behaviour is expected and other users are getting the same messages? Or does this indicate a more serious problem with the MCPC or SCC board?
After sccBmc seems to have run successfully, there is another more severe problem: after invoking "sccBoot -l 0" to start Linux (default image from sccKit 1.3.0), the MCPC freezes immediately after "INFO: Found object for MC x=0, y=0" is displayed. From this point on, the message "BUG: soft lockup - XPU#0 stuck for 61s! [crbifd:735]" is displayed once every minute (please see attached screenshot). The same lockup happens regardless of the SCC core id (and even when trying to start Linux on all cores at once), and regardless of whether I try sccBoot or sccGui. I also tried the memory and controller test from within sccGui, which freezes the MCPC as well.
Does anybody have an idea on how this can be resolved?
For your information: the MCPC is a Dell Optiplex 755 with BIOS A17 (April 2010), running Ubuntu 10.04.1 64bit. The PCIe card is installed in the PEG slot, as this is the only PCIe slot available on the mainboard.
Interestingly, this system does not boot if the SCC is powered on (just stays at a blank screen without any video output; it doesn't even show the Dell logo!). To get the system into booting Linux, I need to start with the SCC powered down, then halt at the GRUB2 menu. I then start the SCC via another computer, wait until the BMC sends the "Done" message, then continue booting Linux on the MCPC.
