as per the messge it rebooted due to PCI issue may be due to bug,

if this frequently happending raise a TAC case for RMA

 - Looks indicative for a hardware problem, you may however look into the current software version being used and or upgrade to an advisory release , if applicable. Check if the problem then becomes persistent or not.

 You already reported that in your initial post :

     #sh reboot history
   >..... 0x0800001f REBOOT_CAUSE_PCIESVR_RESTART

 Look into the current software version being used and or upgrade to an advisory release , if applicable. Check if the problem then becomes persistent or not.
