DL380 BSOD due to CPU microcode revision mismatch??
I have a customer that is experiencing BSOD on a DL380G3 running Windows 2003. They've logged a call with Microsoft and received the following;
The problem was caused by an overwrite of a 32 byte region of the page table. This happens to be the hardware cache granularity for the x86 processor. It looks like it could either have been caused by a faulty driver or a hardware error.
In any event case, it looks like you have a microcode revision mismatch on the two processors. I recommend that you get the latest BIOS flash installed on this machine.
0: kd> !cpuinfo
CP F/M/S Manufacturer MHz PRCB Signature MSR 8B Signature Features
TargetInfo::ReadMsr is not available in the current debug session
0 6,11,1 GenuineIntel 1396 0000001c00000000 00003fff
1 6,11,4 GenuineIntel 1396 0000000100000000 00003fff
The 1C and 10 aren't the same - that's bad, and will need to be fixed via a BIOS update.
Please see:
842465 Stop 7F, 0x00000008 (double-fault) error occurs because of a single-bit error.
Has anyone seen this and does a "System Bios" upgrade effect the CPU Microcode revision??
Thanks,
Chris Velasquez
