We were spending more time on the problem than the system was worth.  We sent the unit to electronic recycling. Problem solved.
The same thing has happened to me two or three months ago, my poweredge just decided to reboot (found a "System CPU resetting" message in lifecycle logs) and got stuck after CPLD version : 103. That time i was able to enter LifeCycle controller, start the diagnostics (which didn't show any hw errors) and to boot again after that. Now that's happened again, but this time i'm unable to enter LifeCycle controller. However i'm able to get into PERC bios, Intel Boot Agent bios and i'm even able to get into iDRAC web interface, to use virtual console. I've been even able to update iDRAC's firmware to the latest. Sadly i'm unable to update any other firmware which requires reboot (including BIOS), since i'm stuck at CPLD. I've googled this topic out, found a lot of proposed solutions, none of them work in this case. Tried to clear nvram (jumper way), tried to take the battery out and wait few days, tried to take CPU #2 out, nothing works. Here are some screenshots: [IMAGE]BIOS version[IMAGE]Booting...[IMAGE]This is where it endsI'm pretty sure it's factory spoilage, since this poweredge usually did a lot of (4-6 times a year) reboots by itself, with the log message "System CPU resetting", but i was quite sure it's a BIOS firmware problem and it's going to be fixed with the next version. And maybe it was fixed, i wouldn't know, as i'm unable to flash the new version. :) Any suggestions?
