Hello list,
The following appeared in the dmesg buffer of my FreeBSD server. From my
reading of x86/x86/mca.c, this means that the CPU had two (correctable)
cache errors. This doesn't help me much, as I don't know what MCA, DRD,
SNOOP and {D,G}CACHE stand for... Is it a transient error? Should I
start screaming at my hosting provider so he changes my CPU?
The box has an Intel Celeron CPU 2.66GHz. It runs FreeBSD 8.2. A dmesg
can be found at <http://tar-jx.bz/stuff/dmesg.papillon>. It is a
'kimsufi' (the cheapest model as of 18 months ago, no longer featured on
kimsufi.com).
