1 Hi guys,
2
3 From a few days ago I am experimenting an MCE error.
4 Sometimes I turn on the computer and at some point while booting the
5 kernel (after the grub menu) just freezes and puts this:
6
7 CPU 0: Machine Check Exception: 4 Bank 4: b200000000070f0f
8 TSC f5acc9180
9 PROCESSOR 2:20fc2 TIME 1427486735 SOCKET 0 APIC 0 microcode 0
10
11 the number for TSC may vary, but the b200000000070f0f it's always the
12 same (at least for now). The error message suggest to parse the above
13 error with mcelog. I did that and the result was:
14
15 Hardware event. This is not a software error.
16 CPU 0 4 northbridge TSC f5acc9180
17 TIME 1427486735 Fri Mar 27 17:05:35 2015
18 Northbridge Watchdog error
19 bit57 = processor context corrupt
20 bit61 = error uncorrected
21 bus error 'generic participation, request timed out
22 generic error mem transaction
23 generic access, level generic'
24 STATUS b200000000070f0f MCGSTATUS 4
25 CPUID Vendor AMD Family 15 Model 44
26 SOCKET 0 APIC 0 microcode 0
27
28 The error suggest it's a hardware problem. I replace de RAM with no
29 luck. Same error keeps happening.
30
31 Any suggestion for identifying the problem or how to procede?
32
33 Many thanks in advance!
