+Subject: [PATCH] Add sufficient delay to create smbios2 file
+
+Issue: Sometimes with existing defaultTimeout & sysClock delay, BIOS is
+not responding with required information to create smbios2 file which
+contains DIMM info.
+
+Fixed: Increase defaultTimeout & sysClock time to provide required delay
+to get response from SMBIOS in order to populate DIMM information.
+
+Tested:
+1. Verified for 100 DC cycles.
+2. smbios2 file is generated for each cycle with proper DIMM information
+
