At this point they seem like different issues so I am opening up 2 different defects. I've already opened up defect SW354759 for the first set of htx errors and assigned to htx_screen. This defect is for issue that happened after 17th reboot (Jun 1 @ 6am). On the 18th reboot (Jun 1 @ 7am), the shutdown -r command failed... I had to manually power down system. I guess I will open to surelock_screen first since it seems similar to the one Dion opened up while running 128 virtual LUNs per port (defect http://w3.rchland.ibm.com/projects/bestquest/?defect=SW353881) . For this fail, other exercisers eventually failed also. Test Info: ============ - running Soft bootme (shutdown -r every hour) - mdt.bu + hxecom (GPUs were running). I copied a modified mdt.bu to another mdt file so I would not see any errors in htx after reboot.
