Partial summary update: ES40: CPU1 VIO warn

Dear all,

There must be something in the air at the
customers site. First I've rotated the CPUs
(there are three of them), because this was
the easiest way to locate the problem. The
warning remained. I've rotated them again,
still "CPU1 VIO warn". Then I removed all the
CPUs, and inserted a fourth one (into slot 0)
with the result "CPU0 vio warn". OK, so it's
not the CPUs causing the problem. The following
combinations
- original CPU MB, original PCI MB;
- original CPU MB, replacement PCI MB;
- replacement CPU MB, original PCI MB;
- replacement CPU MB, replacement PCI MB
_all_ caused "CPU1 VIO warn". If someone told
me this, I wouldn't believe! What else could
I replace? The power supplies, fans, cabling,
or the chassis? Any (more) ideas?

Thank you, regards,
